I want a clean, modern personal portfolio that highlights my programming and development work. The site’s main goal is to showcase projects and key skills clearly and professionally, so hiring managers or collaborators can see what I do at a glance.
Core sections I need:
• A concise “About Me” with space for a headshot and short bio
• A flexible “Projects” gallery where each item links to live demos or GitHub repos and lists the tech stack used
• A skills area with icons or progress bars for the languages, frameworks, and tools I use most
• A simple contact form that delivers messages to my email and shows confirmation to the sender
Responsiveness is important; everything should look sharp on desktop, tablet, and mobile. Smooth scrolling, subtle animations, and fast load times matter more to me than heavy visual effects. I prefer a code-first approach—React, Vue, or vanilla HTML/CSS/JS are all fine if the result is lightweight and easy for me to update later. Please include clear instructions (or a short README) on how to add new projects on my own.
Deliverables:
1. Source code pushed to a Git repository I’ll provide
2. Deployed site link (GitHub Pages, Netlify, or similar)
3. Brief documentation covering setup, customisation, and future updates
4. website ferdiyanto.qd.je
I’m happy to answer questions about branding colours, fonts, or content once we get started and can supply logos or screenshots of projects as needed. Let me know your preferred tech stack and an estimated timeline so we can move forward.
I am building a web-based, AI-assisted platform that streamlines daily operations for a small outpatient clinic. The core of the system is an intelligent appointment scheduler that learns provider availability, suggests optimal time slots, and automatically emails patients a confirmation plus follow-up reminders as the date approaches. Alongside scheduling, I also need a secure patient record module where staff can create, view, and update demographics, visit notes, and basic treatment history in one place.
Role-based access is essential: administrators must control settings and reports, medical staff should handle day-to-day scheduling and chart updates, and patients will log in only to view or book their own appointments. Please architect the permissions cleanly so each user sees only what they need.
I expect a modern UI (React, Vue, or similar), a robust backend (Node, Django, or comparable) with REST or GraphQL APIs, and a lightweight machine-learning component for time-slot optimization—Python libraries such as scikit-learn or FastAPI would fit nicely if you prefer. Data must be encrypted in transit and at rest, and the code should be well-documented for future maintenance.
Deliverables
• Fully functional web application deployed to a test server
• Source code repository with clear README and setup scripts
• Brief walkthrough video or live demo session
Acceptance Criteria
• Users in each role can only access their permitted features
• Appointment emails reach the intended recipient reliably (use a sandbox SMTP for proof)
• System stores, retrieves, and edits patient records without data loss
• Scheduler suggests time slots within 1–2 seconds after availability update
If this aligns with your skill set and you can commit to a two-week sprint for an MVP, let’s discuss your approach and timeline.

We are looking for an experienced React Native developer with strong mobile UI/UX skills to improve and expand an existing mobile application.
The app is already live on the App Store. The immediate focus will be modernizing the interface, improving usability, resolving existing UX issues, and creating a more polished and consistent experience across the app. We also plan to introduce new features over time.
This is not a project that requires rebuilding everything from scratch. We need someone who can review the current codebase, understand the existing product flow, recommend practical improvements, and implement them without disrupting current functionality.
REQUIRED EXPERIENCE
* Strong professional experience with React Native
* Proven mobile UI/UX implementation experience
* Experience improving or modernizing an existing mobile application
* Comfortable working with Firebase
* Experience with subscription-based mobile applications
* Strong understanding of reusable components and scalable architecture
* Experience debugging mobile application issues
* Clear written and verbal communication
* Ability to work independently and provide thoughtful recommendations
The first phase will focus on reviewing the current application, identifying the most important UI/UX and technical improvements, and implementing the agreed priorities.
We are planning to develop several similar applications, so this project has strong potential to become a long-term working relationship for the right developer.
TO APPLY PLEASE INCLUDE:
1. Examples of React Native applications you have built or improved
2. Links to relevant App Store or portfolio projects
3. Your approach to reviewing and modernizing an existing mobile app
4. Your availability and expected weekly capacity
5. If you're a real person, not AI, please begin your proposal with the words “Mobile App.”
We need an independent penetration test of a SaaS web application, its API, and the cloud infrastructure supporting it.
The goal is a thorough, manually driven assessment with a report we can act on internally and share with external stakeholders. We are not looking for automated scan output.
Environment
Web application : SaaS platform, React frontend, REST API backend
Hosting : AWS
Test environment : a staging environment mirroring production
Test scope
Grey-box assessment
External network testing : perimeter enumeration, exposed services, misconfigurations, known vulnerabilities
Web application testing : authenticated and unauthenticated, following OWASP WSTG; injection, authentication and session handling, business logic flaws, file upload handling, client-side issues
Authorization testing : horizontal and vertical privilege escalation, cross-tenant data access
API testing : REST endpoints, rate limiting, input validation, authorization enforcement at the API layer
Deliverables
Test execution : following a recognized methodology (PTES, OWASP WSTG or equivalent)
Written report including:
Executive summary written for a non-technical audience
Scope, methodology, tooling, and timeframe
Findings ranked by severity (CVSS v3.1 or v4.0), each with description, affected assets, evidence/proof of concept, business impact, and actionable remediation guidance
Positive observations / controls that held up
Attestation or summary letter suitable for sharing with external stakeholders such as customers, partners, or auditors
Remediation retest of fixed findings, with an updated report (typically within 30 days)
Report quality matters as much as testing depth. Findings must be clear, reproducible, and free of unfiltered scanner output.
Requirements
- 2+ years of hands-on professional penetration testing experience
- At least one relevant certification: OSCP, OSWE, OSEP, GPEN, GWAPT, CREST CRT/CCT, or equivalent
- Strong command of manual testing techniques
- Proficiency with standard tooling (Burp Suite Professional, Nmap, Metasploit, ffuf, sqlmap, cloud security tooling) - you must have your own licensed tools
- Demonstrated report-writing ability in professional English
- Reliable availability and communication during the agreed testing window (some overlap with North American business hours preferred)
Nice to have
- Depth in AWS security and cloud-native attack paths
- Experience testing multi-tenant SaaS platforms and tenant isolation specifically
- Familiarity with common compliance-driven testing expectations and reporting formats
Client's questions:
Walk us through your methodology for a grey-box web application test
How would you approach testing tenant isolation in a multi-tenant SaaS application?
How do you determine severity when CVSS scoring doesn't reflect real business impact?
Describe how you handle discovery of a critical vulnerability mid-test.

3-Way Inventory PO Invoice and Recipt Matching Web App

Client Rank
- not enough data

We are seeking an experienced developer to build a secure, browser-based application that automates the matching of Purchase Orders, Goods Receipts and Supplier Invoices for our Accounts Payable process.
The application will import Purchase Orders and Goods Receipts from Excel and read supplier invoices (Excel and PDF) stored in Microsoft OneDrive. It should perform intelligent line-by-line three-way matching, identify discrepancies and provide an approval workflow with a complete audit trail.
Key Features
Automated PO–Invoice–Receipt three-way matching
Line-by-line quantity and price comparison
Exception management with configurable tolerance levels
Dashboard showing outstanding matches and exceptions
Role-based user access
Email notifications for exceptions and approvals
Search by Supplier, PO Number, Invoice Number and Product
Audit history of all actions
Export results to Excel/CSV
Preferred Technology
Modern web application
Django + React preferred, or equivalent framework
SQL relational database
Microsoft OneDrive integration
Excel and PDF processing
Developers may recommend an alternative technology stack if they believe it provides a better long-term solution.
Deliverables
Complete source code
Installation on our Windows environment
Documentation
User and administrator guide
Experience Required
Please provide examples of similar workflow, Accounts Payable, inventory or document matching systems.
To confirm you have read this project, please begin your proposal with the words: "RONIS MATCH".
One final suggestion
Increase your budget if you can.
Looking at the scope we've defined, I think:
AUD $700 is likely too low.
AUD $1,200–$2,000 is a more realistic range for a good quality Stage 1 application.
If you receive bids around AUD $1,500, don't dismiss them—they may represent much better value if the developer has relevant experience in business workflow systems.
Given how much manual work this application could save, investing a bit more upfront in the right developer is likely to pay off.
How to Bid (For Freelancers)
Please reply with a proposal detailing:
1. Your suggested tech stack for handling the web interface and PDF/OCR invoice
parsing.
2. Your architectural approach to handling the Excel supplier invoice format
variance challenge (e.g., whether you recommend building a custom translation
template mapping layer per supplier or a dynamic algorithmic scenario mapping
engine).
3. A realistic breakdown of milestones and timeline for Stage 1.
Please start your bid with the word "RONIS MATCH" so I know you have read these
requirements completely.

Accounting & Consulting, Recruiting & Human Resources
I already have a full-stack clinic management web application built with React, but the polish just isn’t there yet. Before I put it in front of paying customers I need two things tightened up:
First, the overall look and feel. Navigation flows need to be clearer, the layout needs to breathe, and the visual design should feel cohesive across every page. Subtle micro-interactions will go a long way toward making the experience feel professional, so I’m open to tasteful animation or hover states where they genuinely improve usability.
Second, the login and registration flow must work flawlessly. Right now some users are unable to create an account or log in consistently, which is obviously a show-stopper. I need robust, error-free authentication (email + password) that plays nicely with the existing user and subscription logic already in place.
Because this will be sold as a turnkey clinic solution, I consider the project complete only when a brand-new user can:
• Sign up, confirm their account, and log in without errors
• Navigate intuitively through the dashboard, appointments, billing, and reports modules
• Enjoy a clean, modern UI that looks consistent on desktop and tablet
• Log out and back in again with session persistence behaving as expected
Hand-off should include the updated React source, any new component or style libraries you introduce (documented in package.json), and a short readme so I can spin up a demo instance immediately.
If this sounds like your wheelhouse, let’s get the app ready for showtime.

I’m building an online mentorship hub for MBA students and need a developer who can take the project from code to live deployment using Next.js, React and TypeScript. The site must feel modern and minimalist, with the color scheme from my reference sites treated as the main design anchor so everything—from the landing hero to the smallest button—matches that palette consistently.
Core sections
• Landing page: sleek, fast-loading, clean navigation, built for conversion and readability.
• Blog: SEO-friendly routing, easy Markdown or CMS-based editing so I can publish new educational pieces quickly.
• Courses page: dynamic list of offerings that shows descriptions, pricing and triggers a Razorpay checkout flow without page reloads.
• Contact + social: simple form that funnels to my email, plus embedded LinkedIn, Twitter and Instagram icons.
Cross-device responsiveness is non-negotiable, and the codebase should be structured for painless feature additions down the road (think modular components, clear state management and sensible folder architecture). When everything is ready, push the build to my hosting server and confirm that payments run end-to-end in production.
Deliverables
1. Clean, commented source code in a Git repo
2. Fully functional Razorpay integration
3. Live, deployed website on my server
To move forward, share links to comparable React/Next.js projects you’ve shipped, along with your estimated timeline and total cost. Fast performance, tidy code, and the possibility of long-term collaboration matter most to me, so highlight any practices or tooling you use (e.g., TypeScript strict mode, Lighthouse tuning, CI/CD pipelines) that reinforce those goals.

I have a fully-coded utility application that needs to go live. Your first task is to recommend and purchase a private hosting plan with the most competitive rates—whether that turns out to be AWS, Google Cloud, Azure, or another reputable provider is up to you, as long as you justify the choice on price-to-performance and long-term scalability.
Once hosting is secured, I’ll hand over the source for both backend and frontend. You will:
• Configure the server, set up the chosen tech stack, and deploy the backend APIs and database.
• Launch the frontend so it is accessible via a custom domain and works seamlessly with the backend.
• Provide clear environment docs (DNS settings, SSL, environment variables, build commands) so I can replicate or scale later.
• After web deployment is stable, wrap the same codebase into an APK, sign it, and supply the final build ready.
Acceptance will be based on:
1. Live web app reachable from the custom domain with HTTPS enabled.
2. Backend endpoints returning expected data without 4xx/5xx errors.
3. An installable, fully functional APK built from the same codebase and validated on at least one physical Android device.
Please outline the hosting plan you’d select, your deployment workflow, and the tools you propose (CI/CD, containerization, PWA wrapper, React Native, Expo, etc.) so I can give the go-ahead quickly.

I am building a WordPress-based platform and need a developer who is completely comfortable working in PHP and the WordPress ecosystem. The immediate milestone is a robust, responsive admin dashboard that lets non-technical staff manage content, users, and key site settings without ever touching code.
Beyond the dashboard itself, I expect best-practice coding: clean architecture, secure queries, proper use of hooks, and thorough inline documentation so future contributors can navigate the project easily. Any custom functionality should remain portable and follow WordPress coding standards.
You will frequently interact with third-party REST APIs, so well-structured cURL/HTTP calls, token handling, and error logging are part of the work. Although the core stack is WordPress + PHP, familiarity with JavaScript (vanilla or React), MySQL optimisation, and tools like Git is important because performance and maintainability matter just as much as features.
Please focus your proposal on relevant experience: similar dashboards you have built, plugins you’ve customised, and any security or performance wins you can quantify. Strong, proactive communication and reliable, on-time delivery are essential.
Key deliverables
• A fully functional, mobile-friendly WordPress admin dashboard with role-based access
• Clean, secure PHP code following WordPress standards and documented inline
• API integration for designated third-party services, including error handling and logging
• Deployment instructions and a short hand-over walkthrough (video or written)
If this first phase goes smoothly, there is scope for further enhancements—e-commerce modules, custom features, and performance optimisation—so I’m looking to establish a long-term collaboration.

• Stripe integration
• QuickBooks integration
• PDF generation
• Authentication
• Experience building production SaaS applications
## We Are Looking for Someone Who
• Writes clean, maintainable code
• Communicates well
• Has built production SaaS applications
• Can work independently
• Can collaborate effectively with another developer
## To Be Considered, Please Include
1. Links to two live SaaS applications you personally built.
2. A brief description of exactly what you built on each project.
3. Your GitHub profile (if available).
4. Begin your proposal with the word "Radiology" so I know you read the job posting.
This project has a detailed specification. We are looking for developers who can execute efficiently, not spend weeks defining requirements.
There is strong potential for ongoing work for the right developer after the initial build.
THE ROLE
Terra Notes is a bootstrapped B2B SaaS for private and seller-finance lenders: loan servicing, ACH payment collection, borrower management, subscription billing. We have live customers and real money moving every day. You'd be our second backend engineer, working alongside our existing lead and reporting to our Head of Product & Development.
This is an ownership role, not ticket-taking: take a product goal, architect the right approach in our environment, and own delivery end to end, durably, the first time.
THE STACK
- Python on AWS serverless
- Lambda functions via AWS SAM, Pipenv, pytest
DynamoDB, Cognito (auth), API Gateway, SES, S3, Secrets Manager
- Payments & verification: our ACH processor (ACH), Plaid (identity/verification), Authorize.net via Kurv (card)
GitHub Actions CI/CD, Jira (SCRUM)
WHAT YOU'LL OWN FIRST
- Amortization engine hardening — fix payment-override re-amortization (loans must close to zero), payoff-as-of-any-date quoting, and effective-dated backdated payments with a full audit trail
- Escrow module — ledger, escrow-first payment allocation, annual RESPA analysis engine, sweep routing
- Advanced custom loans — step/variable rates, interest-only rollovers, per-diem payoff, custom schedule upload
- General backend reliability on payment, billing, and verification flows
WHAT WE'RE LOOKING FOR
- 4+ years shipping production backend systems in Python
- Real AWS serverless experience — Lambda, API Gateway, infrastructure-as-code (SAM). Please only apply if you've built and shipped serverless, not just monolithic web apps
- Comfort with money-touching code: idempotency, reconciliation, dry-runs, staging verification before prod. You treat anything touching billing or all-customer data with extra care
- Disciplined habits: testing, PR review, no cowboy deploys
- Direct, honest communication — you flag problems early and you don't hide mistakes. This matters more to us than any single skill
- Strong written English and reliable overlap with U.S. business hours
NICE TO HAVE
- Fintech, payments, or loan-servicing background, Plaid, or Authorize.net integration experience
- Amortization / interest-calculation or accounting-systems experience
HOW WE HIRE
We start with a small paid trial project (real work, real pay) before any ongoing commitment. It's the fastest honest way for both sides to know if this is a fit. Details below.
TO APPLY
Send a short note (skip the generic template) covering: (1) a money-touching or data-critical backend system you've shipped and how you made sure it was correct, (2) your AWS serverless and any payments/fintech experience
(3) a time you caught or surfaced a serious bug before it caused damage, and what you did.
Client's questions:
1. Describe a money-touching or billing system you've built in Python. How did you make sure the financial calculations were correct?
2. Tell me about a time you shipped a bug to production, or nearly did. How did you catch it, and what did you do?
3. Have you built and shipped on AWS Lambda + API Gateway with infrastructure-as-code (SAM or similar)? Briefly describe the system.
4. Have you integrated Dwolla, Plaid, or a comparable ACH/bank-verification API? Which, and what did you build?
5. What are your working hours in your timezone, and how much overlap do you have with US Central (Texas) business hours?

We own several WordPress sites that rank well in organic search, and we're rebuilding them on Lovable. The sites will launch on the same domains. Our number one priority is that we do not lose rankings, traffic, or indexed pages in the process.
We're looking for someone who has actually done this before, not someone who is going to learn on our sites.
Scope:
Multiple sites, each with a large number of URLs including substantial blog archives
Full URL path parity between the old and new builds, or a properly mapped redirect plan where parity isn't possible
Preservation of on-page SEO elements: title tags, meta descriptions, headings, canonical tags, schema markup, image alt text, internal linking structure
XML sitemaps, robots.txt, and structured data carried over correctly
A plan for how Lovable's rendering approach will be handled so that Google can crawl and index the new pages properly
A blog/content strategy, since Lovable is not a CMS in the way WordPress is. We want to hear how you'd handle ongoing publishing
Pre-launch crawl and benchmark, then post-launch monitoring in Google Search Console for indexation drops, crawl errors, and ranking movement
What we want in your proposal:
Describe a WordPress to Lovable (or WordPress to React/SPA) migration you've personally handled. Include the site size and what happened to traffic in the 90 days after launch.
Tell us your recommended strategy for this specific situation. What is the biggest risk you see, and how do you mitigate it?
List the tools you use for crawling, mapping, and monitoring.
Give us your estimated timeline and how you'd want to structure the engagement.

We're a small product team looking for one reliable developer on an ongoing monthly retainer. We maintain two products: an Expo (React Native) mobile app and a React / Next.js web app. You'd own feature work across both.
How we actually work, so there are no surprises:
- Tasks are written up in Notion with context and acceptance criteria.
- You pick up the task, set up your own local environment, and build it — using Claude Code, Cursor, or whatever AI tooling you prefer. We're not precious about how the code gets written.
- You test it properly. Not "it compiled." You run the flows, check edge cases, and confirm it works on device / in the browser before anyone else sees it.
- You open a PR with a clear description of what changed and what you verified.
- Our senior developers review and merge to production.
- Weekly team sync (~30 min) to align on priorities.
This is roughly 5-10 hours a week — light and steady, not a firehose. What matters far more than hours is that when you say something is done, it's done.
WHAT WE'RE LOOKING FOR
- Real React fundamentals from before AI wrote code for you. You can read a component tree, debug a state issue, and explain why a re-render is happening without asking a model. AI accelerates people who already know what they're doing; it hides the gaps in people who don't.
- Solid React Native / Expo experience — builds, native modules, EAS, device testing.
- Comfortable in a codebase you didn't write. You read before you change.
- Fluent with AI coding tools and honest about their failure modes. You review output instead of pasting and hoping.
- Clean Git and PR hygiene — scoped changes, descriptions a reviewer can follow.
- Strong written English, responsive. If you're blocked, we hear about it that day — not at the weekly sync.
NICE TO HAVE
TypeScript, Supabase/Postgres, App Store / Play Store releases, Jest / React Native Testing Library / Playwright.
THE ENGAGEMENT
$1,000/month, paid via monthly milestones, ongoing. Starts with a small paid trial task. If it works, there's substantially more here — larger scope, more ownership, and this could become full time.
TO APPLY
Skip the generic proposal, we don't read those. Instead:
1. Start your reply with the word PIXEL so we know you read this.
2. Describe one feature you shipped in React Native/Expo, and specifically how you tested it before shipping.
3. Which AI coding tools you use daily, and one time the model gave you something confidently wrong that you caught.
4. Your availability and time zone.

# Senior Product Builder Needed to Create an AI-Powered Personal Operating System
I’m looking for a senior product-minded engineer or small team to help design and build a private AI-powered personal operating system.
This is not a basic note-taking app, chatbot, or collection of automations.
The goal is to create one central system that understands everything happening across my work and personal life, keeps the context organized, helps me think, and makes sure important things do not get dropped.
Think of it as a combination of:
- Evernote or Notion for long-term memory
- ChatGPT as a strategic thought partner
- Town.com as a deeply personalized assistant
- Granola as meeting memory
- A CRM for relationships and sales opportunities
- A chief of staff for priorities, commitments, and follow-through
- A task manager that understands where the tasks came from
- A searchable archive of emails, meetings, documents, ideas, and decisions
The system should gradually become an all-knowing “Rob OS” that understands my business, relationships, projects, communication style, decisions, priorities, and patterns.
## What I Want the System to Do
Information should flow into the system automatically from sources including:
- Gmail
- Google Calendar
- Granola meeting notes and transcripts
- Our CRM
- Sales decks
- Proposals and contracts
- PDFs, spreadsheets, and other documents
- Slack
- ChatGPT conversations
- Voice notes
- Screenshots
- Web links
- Notes created directly in the system
The system should automatically understand and organize that information.
It should identify:
- People
- Companies
- Projects
- Sales opportunities
- Tasks
- Commitments
- Decisions
- Deadlines
- Risks
- Open questions
- Ideas
- Follow-ups
- Important changes
I should not have to manually tag, file, and organize everything.
## How I Want to Use It
I want to be able to ask questions such as:
- What should I focus on today?
- What am I missing?
- What have I promised people this week?
- What is waiting on me?
- What am I waiting on from someone else?
- Which sales opportunities are going cold?
- What risks are developing across the company?
- What did we decide about this project?
- Why did we make that decision?
- What has changed since my last conversation with this person?
- What objections has this prospect raised?
- What patterns are showing up across my sales calls?
- Where am I becoming the bottleneck?
- What am I avoiding?
- Prepare me for my next meeting.
- Debrief the meeting I just had.
- Draft the follow-up in my voice.
- Challenge my thinking on this decision.
- Turn this idea into a plan with owners and next steps.
The answers must be based on my actual emails, meetings, notes, documents, CRM activity, and prior decisions.
Every answer should link back to the original source so I can open the email, meeting, deck, note, or document it came from.
## The User Experience
This needs to work well on both desktop and mobile.
Capturing information should be nearly effortless.
I should be able to:
- Forward an email
- Record a voice note
- Share a screenshot
- Upload a deck
- Save a link
- Drop in a document
- Type a quick thought
The system should save it immediately and organize it in the background.
I also need a real interface where I can browse and search the underlying information. I do not want everything trapped inside a chatbot.
The system should include clear views for:
- Today
- Inbox
- Projects
- People
- Companies
- Sales opportunities
- Tasks
- Decisions
- Meetings
- Resources
- Archive
- Search
- Ask Rob OS
Search needs to be fast and should return the actual notes, emails, meetings, and documents, not only an AI-generated answer.
## The Intelligence Layer
The system should do more than summarize information.
It should continuously maintain an understanding of what is happening.
For example, it should recognize when:
- A project is slipping
- A prospect’s attitude has changed
- A commitment is overdue
- A relationship has gone quiet
- A deadline has moved
- An opportunity is losing momentum
- A new risk has appeared
- Someone has changed their position
- I am contradicting an earlier decision
- The same problem keeps happening
- I am repeatedly becoming the bottleneck
It should be able to act as several different types of partner depending on what I need:
- Strategic sounding board
- Chief of staff
- Sales coach
- Leadership coach
- Writer and editor
- Research assistant
- Decision partner
- Red team that challenges my preferred answer
- Historian that remembers what happened and why
I do not want an assistant that simply agrees with me. I want a system that can identify weak thinking, inconsistencies, and blind spots.
## Proactive Support
The system should eventually provide:
### Daily Brief
A concise view of:
- What matters today
- Upcoming meetings
- Important emails
- Commitments due
- Tasks that need attention
- Opportunities that need movement
- Projects at risk
- Relationships that need follow-up
- Important changes since yesterday
- What I can safely ignore
### Meeting Preparation
Before a meeting, it should show:
- Who I am meeting
- Our relationship history
- Previous conversations
- Open commitments
- Relevant emails and documents
- Current project or sales context
- Questions I should ask
- Risks I should be aware of
- The outcome I should try to achieve
### Meeting Debrief
After a meeting, it should identify:
- What happened
- What changed
- Decisions
- Tasks
- Commitments
- Risks
- Opportunities
- Follow-up needed
- Recommended CRM updates
- A draft follow-up email
### Weekly Review
It should summarize:
- Wins
- Misses
- Decisions made
- Decisions still needed
- Projects on track
- Projects at risk
- Missed commitments
- Pipeline movement
- Relationship changes
- Repeated issues
- Recommended priorities for the following week
## Important Product Principles
The system must be:
- Fast
- Simple to use
- Highly searchable
- Easy to capture information into
- Reliable across desktop and mobile
- Grounded in original sources
- Private and secure
- Able to separate personal and business information
- Auditable
- Reversible when AI makes changes
It should not become another giant pile of notes.
Every piece of information should have a clear home and should connect to the relevant people, projects, companies, meetings, decisions, and tasks.
The AI should organize the system, but it should flag uncertainty rather than confidently filing something incorrectly.
## What I Need From You
I am not looking for someone who will immediately start coding from a loose idea.
I need someone who can help turn this vision into a well-designed product and then build it.
The engagement should begin with:
1. Product definition and prioritization
2. User flows and interface design
3. A clear plan for how information enters and moves through the system
4. Definition of the major objects such as people, companies, projects, meetings, opportunities, tasks, decisions, and commitments
5. A realistic MVP
6. Integration planning
7. Privacy and permissions planning
8. A phased development roadmap
9. A working prototype
10. Production development after the core experience is validated
I expect the right person to challenge parts of this idea and recommend simpler or better approaches where appropriate.
## The First Version
The first version should likely focus on:
- Email
- Calendar
- Granola
- Documents and sales decks
- People
- Companies
- Projects
- Sales opportunities
- Tasks
- Decisions
- Commitments
- Search
- Meeting preparation
- Meeting debriefs
- Daily briefing
- A conversational interface grounded in the underlying information
I do not need every possible integration on day one.
I would rather build a smaller system that works extremely well than a massive system that feels unreliable.
## Who I Am Looking For
The ideal person has experience building products involving several of the following:
- AI-powered applications
- Personal knowledge systems
- Search
- Email and calendar integrations
- CRM integrations
- Meeting intelligence
- Workflow automation
- Data organization
- Productivity software
- Executive or enterprise tools
- Secure applications containing sensitive information
You should be comfortable thinking across product strategy, user experience, system design, and implementation.
I am especially interested in senior builders who can work directly with a founder, make strong product decisions, communicate clearly, and independently drive the project forward.
This is not a good fit for someone who only wants a detailed list of tickets to execute.
## How to Apply
Please include:
1. A short explanation of how you would approach this project.
2. Examples of relevant products or systems you have built.
3. Which parts you would build first and which parts you would delay.
4. The biggest product or technical risks you see.
5. Whether you would handle product design and engineering yourself or work with a team.
6. Your expected availability.
7. Your preferred engagement structure.
8. A rough estimate for the product-definition and prototype phase.
Please begin your response with the sentence:
“I understand that this is an operating system, not a notes app.”

I’m looking for an experienced mobile app developer or small development team to build the MVP of a two-sided service marketplace application for iOS and Android.
The platform will allow users to submit service requests and connect with independent service providers who can accept, complete, and track those requests. The full business model and proprietary features will be shared after an NDA is signed.
Initial MVP Scope
The application will likely include:
* Customer and service-provider account creation
* Simple request submission process
* Provider request acceptance and management
* Location-based matching
* Real-time status updates and basic tracking
* In-app messaging
* Push notifications
* Payment processing
* Ratings and reviews
* User profiles and request history
* Basic administrative dashboard
The interface should be modern, extremely simple, and easy to use. The goal is to avoid an overly complicated marketplace experience.
Preferred Technology
I am open to recommendations, but Flutter or React Native is preferred so the application can be developed efficiently for both iOS and Android.
The developer should also be comfortable with:
* Firebase, Supabase, or a similar backend
* Secure payment integrations
* Maps and location services
* Push notifications
* Scalable database architecture
* App Store and Google Play deployment
Who I’m Looking For
The ideal candidate has:
* Experience building marketplace, delivery, gig-economy, or on-demand service apps
* Strong mobile UI/UX judgment
* Experience developing both customer-facing and provider-facing workflows
* Clear written and verbal communication
* The ability to recommend cost-effective MVP solutions
* A willingness to sign an NDA before receiving detailed business information
I am currently focused on building a functional and visually polished MVP—not an unnecessarily large or expensive first version.
### When Applying, Please Include
1. Examples of similar mobile applications you have built
2. Whether you work independently or with a team
3. Your recommended technology stack
4. A general estimated timeline and budget range
5. What you would include in the first MVP
6. Whether you provide UI/UX design, development, testing, and deployment
7. Confirmation that I will receive full ownership of the source code and intellectual property
Please begin your proposal with the word **“MARKETPLACE”** so I know you read the full posting.
Additional details will be shared with qualified candidates after an initial conversation and NDA.
I am looking for a 25 to 30 page website with specific landing pages. You could take a look at what we have right now to give you an idea our initial website is www.gridlineelectricco.com We are looking for a complete friendly home service, electrical design and specifically with red white and blue color scheme. There is a company called new light electrical services that you can look up online and they have a really nice friend friendly welcoming Design we’re looking for something like that.
Our mobile app is live and gaining traction, but the immediate focus is to accelerate user acquisition through targeted social media marketing. I need a partner who can design and execute a data-driven strategy across the key platforms where our audience already spends time, then translate that engagement into installs and active users.
Scope of the first phase
• Audit our current social presence and analytics setup
• Develop a campaign roadmap with clear growth KPIs (follower uptick, CTR to store pages, CPI targets, retention metrics)
• Produce platform-specific creative, copy, and ad sets
• Launch, monitor, and optimize paid and organic initiatives in real time
• Deliver weekly performance reports that highlight insights and next steps
What to send with your bid
A detailed project proposal is essential. Walk me through the tools you plan to use (e.g., Meta Ads Manager, TikTok Ads, Buffer, Hootsuite, GA4, Mixpanel), the milestones you foresee, and the metrics you will own from day one. Past work and credentials are welcome but only as context for the plan you outline.
Next phases
Once the marketing engine is humming, I have a queue of app bug fixes and broader scaling tasks. If your team can also tackle React Native issues, backend performance, or infrastructure hardening, let me know—an integrated solution is a plus, though not mandatory for this engagement.
Acceptance criteria for the initial sprint
• Strategy deck and content calendar approved
• Campaigns launched on at least two social channels within two weeks
• First report demonstrating baseline metrics and optimization actions
Let’s boost our visibility, turn views into users, and set the stage for smoother scaling down the road.
(the app is called The Skin Sanctum, if you want to contact me you can reach me at the email provided on the website.)

We’re looking for a senior full-stack developer to help with an existing production booking app.
Lesson Connection is a live lesson-booking platform with a web portal and mobile app. The product is used by coaches, players, and sports facilities to manage private lessons, court scheduling, and payments. We’re starting to get more traction and have active lessons coming in, so we’re looking for someone reliable who can help stabilize the product now and potentially support ongoing feature work as we grow.
This is not a rebuild. We need someone who can step into an existing codebase, review production behavior, debug backend/mobile/API issues, and help us move quickly but carefully.
The first phase would be a paid diagnostic/review of two current production issues. After that, we would like to move into the actual fixes, and if it’s a good fit, there is strong potential for ongoing maintenance and feature development.
1. Invite flow issue
In the web portal, when a facility owner adds a coach/facility user, the person shows as pending, but the invite does not appear to send. We checked Twilio logs and there is no message, so it seems like the backend may not be calling Twilio.
2. Court conflict issue
Court conflicts appear to work correctly in the web portal, but not in the mobile app booking flow. If one coach has Court 1 booked at a facility, another coach/player booking flow should show Court 1 as unavailable/conflicting for that same time.
First paid phase:
* Review the two issues
* Identify likely root causes
* Explain findings clearly
* Estimate the time/cost to fix
* Recommend the best next steps
Potential ongoing work:
If the diagnostic/fix work goes well, we are interested in continuing with the right developer for additional maintenance and feature improvements. Some future areas may include onboarding improvements, booking/calendar enhancements, better facility/coach management, reporting, and possible calendar integrations.
Ideal experience:
* Laravel/PHP
* React Native/Expo
* Twilio SMS/invite flows
* Stripe/payment systems
* REST APIs
* MySQL/database relationship debugging
* Existing production app maintenance
* Booking, scheduling, or calendar logic
We’re looking for someone who is:
* Reliable and clear in communication
* Comfortable working async
* Good at debugging existing systems
* Able to explain findings in plain English
* Careful with production code
* Interested in potentially supporting ongoing improvements if the first phase is a good fit
Please include:
* Relevant Laravel/PHP experience
* Relevant React Native/Expo experience
* Any Twilio/Stripe experience
* Examples of existing production apps you have debugged or maintained
* Whether you are comfortable starting with a paid diagnostic before moving into fixes
Client's questions:
Have you worked on an existing Laravel/PHP production app before? Please briefly describe the type of app and what you debugged or maintained.
Have you worked with React Native and/or Expo? If yes, what kind of production app was it?
Have you debugged Twilio SMS/invite flows before? What would you check first if a pending user is created but no Twilio log appears?
This first phase is a paid diagnostic before moving into fixes. Are you comfortable reviewing the code/API/database flow first, explaining the likely root cause, and then estimating the fix?
I have an iOS app called CarAtlas that's mostly built. I'm looking for an experienced React and Capacitor developer to finish the last pieces and prep for release. Primary tasks are completing Google sign-in, sign in with Apple and email auth, getting iOS push notifications working, resolving any deployment or Git issues, and testing the app end-to-end to document and fix bugs. The app is already functional in many areas. This is a finishing project, not a from-scratch build. Please include examples of similar work, your estimated timeline, and a fixed price quote after review.
We're a Canadian battery manufacturer looking for an experienced mobile developer to build a native iOS and Android app that connects to our lithium batteries over Bluetooth Low Energy (BLE) and displays their live status.
Important: this is an integration and UI build, not a reverse-engineering project. The BLE protocol is already fully reverse-engineered, documented, and validated on real hardware. You will be given a complete protocol specification, a tested reference decoder, and known-good data captures from real batteries. Your job is to build a clean, well-architected app around that proven foundation — not to figure out the protocol.
What the app does (v1 scope):
Scans for and connects to our batteries over BLE
Displays live status: state of charge, voltage, current, temperature, cycle count, and individual cell voltages
Displays fault/warning conditions (over-voltage, under-voltage, over-current, temperature faults)
Allows renaming a battery (display label only)
Simple contact screen and app-info screen
A full written specification with every screen, every data field, and the acceptance criteria will be provided to the selected developer.
Requirements (please read before applying):
Proven experience building BLE apps that connect to physical hardware devices. This is essential. In your proposal, tell us about a specific app you built that talked to a real BLE device, and how you handled connection stability and reconnection. Applications that don't address this will not be considered.
Native iOS and Android delivery. We're open to Flutter or React Native (one cross-platform codebase) — tell us your preference and why.
Modern Android implementation that scans without requiring location permission (Android 12+ neverForLocation).
All source code delivered to our repository. We own the code, accounts, and assets.
How we work:
Single fixed-price milestone: payment is released when the finished app is delivered and verified working on our real batteries — not on partial progress. We verify the code against the provided reference decoder and known-good captures, and we test the app live on physical battery packs before acceptance.
Clear spec, responsive communication, and honest cross-checking. We'll give you everything you need to succeed.
Future potential: This is v1 of an ongoing product. A successful v1 leads directly to further paid phases with the same developer — cloud fault-history logging, warranty features, and more. We're looking for someone we can build a long-term working relationship with, starting with a well-executed v1.
If this sounds like your kind of project, tell us about your relevant BLE hardware experience and your recommended approach.
Client's questions:
Describe a specific app you built that connected to a physical device over Bluetooth Low Energy (BLE). What was the device, and how did you handle connection stability and reconnection when the device dropped or went out of range?
For this project, would you use Flutter, React Native, or fully native (Swift + Kotlin), and why?
This project provides a documented, pre-tested BLE protocol and reference decoder — it's an integration and UI build, not reverse-engineering. Given that, roughly how long do you estimate v1 (iOS + Android) would take, and what would be your first steps?

Website Developer – Next.js Site Rebuild (Finish & Launch)
About the Project:
We're a boutique creative agency rebuilding our company website on a modern stack. The architecture is five pages, credibility-first positioning, with a distinct homepage hero concept already designed. Development is underway; we need an experienced developer to pick it up from its current state and carry it to launch.
Scope of Work:
- Continue development on an existing Next.js + Tailwind + Sanity codebase (repo and current build will be shared with the selected candidate)
- Implement remaining page templates and components against the existing design direction
- Wire up CMS schemas and content modeling for the remaining pages
- Build out animation/interaction work using Framer Motion and GSAP per existing patterns
- QA across devices and browsers, performance and accessibility pass
- Deploy and support launch
Timeline:
We're looking to go from current state to launch in 4 weeks or less. This is a tight, focused sprint, not an open-ended engagement.
AI-Assisted Development Expected:
We use AI coding tools (Claude Code and similar) as a core part of our own development workflow, and we expect candidates to do the same to hit this timeline. Comfort directing AI tools for scaffolding, debugging, and iteration is a plus, not a red flag. What matters is that the output is clean, correct, and matches our design and code standards, however you get there.
Requirements:
- Strong hands-on experience with Next.js and React
- Solid Tailwind CSS skills
- Experience with Sanity (or comparable headless CMS) content modeling and integration
- Experience with Framer Motion and/or GSAP for interaction/animation work
- Comfortable working from an existing codebase and design system rather than starting from scratch
- Strong communication; able to work async across time zones with periodic syncs
- Portfolio of shipped marketing/brand sites, bonus if agency or design-forward work
To Apply:
Please include:
1. 2-3 examples of similar Next.js/Sanity site builds you've shipped
2. Your availability and estimated hours/week over the next month
3. A brief note on your workflow when using AI coding tools
Client's questions:
Include a link to your GitHub profile and/or website
What frameworks have you worked with?
Describe your approach to testing and improving QA
Describe your recent experience with similar projects
