I already have a valid ALIPAYJSESSIONID cookie from my DANA account and need a lightweight, self-hosted API that makes practical use of that single session cookie for authentication.
The core purpose is to pull reliable transaction history—from recent top-ups to payments—so I can integrate the data into my own dashboards. No need for full payment processing or balance checks right now; I’m strictly focused on retrieving past transactions once I’m logged in via the session cookie.
Here’s what I expect:
• A small codebase written in PHP or JavaScript (Node.js is fine) that logs in with only the supplied ALIPAYJSESSIONID and exposes clean REST-style endpoints—at minimum /transactions with date-range parameters.
• Clear instructions on how to set, refresh, or rotate the cookie, plus any headers that DANA expects.
• Error handling for expired or invalid cookies and rate-limit responses.
• A quick README or Postman collection so I can test the calls instantly.
I’ll consider the job complete once I can drop the code onto my server, insert my cookie, hit the /transactions endpoint, and receive the same data the official app shows—parsed into JSON with timestamps, amounts, and descriptions.

# 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.”
This will help me identify applicants who have read the full description.
Upgrade Server Software Versions inside Docker container
Applied

3 hours ago
Client Rank
- not enough data

I need the core server software inside my AzuraCast-based Docker image brought up to date right away. TypeScript, PHP and MySQL are the priority, but I also expect you to bump Vue, Nginx, Redis and any other packages required for a clean, secure build.
1. The upstream official Azura Cast code https://github.com/AzuraCast/AzuraCast/
2. My custom code - version of Azura Cast https://github.com/eternityready2/AzuraCast
You will compare # 2 (my code) to # 1 upstream to see what versions of Nginx etc they use. If they use latest or there is a newer version that is stable for nginx etc. You will apply these upgrades to software in # 2 (my git container).
Also you need to let me know if there is any security patches or good features from the commits of the upstream official azura cast git that my custom azura cast can benefit from. I will decide if you will add those!
This is urgent and quick deadline. You must start now. I think this project will not take more than 2 hours.
You will receive:
• read-only access to the official AzuraCast Git repository so you can mirror their current versions and spot recent security patches and nice features you think I can benefit from.
• write access to my custom azura cast code on GitHub
• SSH access to the VPS that hosts the container
Workflow is simple: pull the upstream tags, adjust the Dockerfile / docker-compose overrides, rebuild, then push a tested branch to my repo. No custom configuration (except a proxy url in nginx) is needed beyond what AzuraCast ships by default; the container must start and pass its own health checks. Once everything is running, commit the updated lockfiles and a concise changelog of what changed and why.
Acceptance criteria
• Container builds without errors on the VPS
• AzuraCast UI loads and can stream a test playlist
• php -v, tsc -v and mysql --version reflect the new versions
• No regressions in existing custom features (a quick smoke test is enough)
• All changes pushed to my GitHub fork via a single, squash-ready PR
This is a hands-on, real-time task; I will be online to provide credentials and review as you progress. Please be ready to start immediately and, per project rules, do not use AI tools while performing the work.

We're building the API/middleware layer for a new workforce product,
Scope covers: onboarding form endpoints (a master company profile plus three product-specific supplements), the full B2C assessment submission and payment flow, a team self-serve commercial path, an in-app notification system, certificate/evidence handling for completion tracking, and an internal admin extension for our own staff — all connecting to a Supabase backend (a separate project from the one used for Accelerator).
This is structured as six clearly-scoped milestones, with full technical specification, schema references, and acceptance checklists provided in the attached brief. Payment gateway is Stripe. Three frontend reference files (the actual onboarding forms and app screens) will be provided alongside the brief so you're building against real code, not just field-name summaries.

I am looking for an equity technical partner to design and build apps.
I prompt my idea/prototype on ai paltform first then a dev need to build it.
Would you like to join me this in this journey?
I will do the distribution. We split the profits . let me know if you are interested.
I’m building a web application from scratch inside Replit and I need it reliably deployed to AWS when it’s ready. The coding will all happen in Replit’s cloud IDE; what I’m looking for is a freelancer who can connect the dots so that every push (or manual trigger) ships the latest build to my AWS account.
Scope of work
• Set up or refine the Replit workspace so the app runs locally in that environment without errors.
• Create a clean, repeatable deployment workflow—GitHub Actions, Replit Deployments, or another proven CI/CD method—that packages the app and launches it on AWS (Elastic Beanstalk, ECS, or plain EC2, whichever you recommend for speed and cost).
• Configure AWS resources, environment variables, security groups, and SSL so the site is reachable at my domain.
• Hand over concise documentation and a short screen-share walk-through so I can redeploy or troubleshoot on my own.
Acceptance criteria
1. A single command or commit automatically builds and deploys the web application from Replit to AWS.
2. The live URL loads the same app version that runs in Replit.
3. All project files and scripts are committed back to the repo with clear comments.

We're looking for a developer to build a B2B platform for bridal and groom dress retailers. The platform connects sellers who have unsold stock with buyers who are looking for it. It does not handle any sale or financial transaction itself. It's purely a search-and-contact tool: once matched, the parties negotiate price and terms privately, outside the platform.
The functionality is asymmetric: sellers upload what they have available (brand, collection, model, size, quantity), while buyers upload nothing, they simply run real-time searches by typing in brand, collection, model, and size to see if anyone has what they need in stock. There's also a separate, more open section dedicated to bulk lots, freely described by whoever wants to offload them, which buyers can browse and filter.
An important point: the business model is based on an annual fee per individual user/account, so it's essential to prevent multiple people from sharing the same login credentials. We need a control mechanism (e.g. IP-based, device fingerprinting, or another solution the expert considers more effective and less invasive) to detect and prevent a single account being shared across multiple users/companies.
The project is split into two phases:
Phase 1: Beta Version: a functional but reduced version, meant to be used to pitch the project to potential users/investors. It should include the core features (seller stock upload, real-time buyer search, bulk section) on a small-scale database, without any secondary features that aren't essential to demonstrate how it works.
Phase 2: Full Platform: development of all remaining features (including security/anti-credential-sharing mechanisms, optimizations, and everything needed for actual launch).
Once the platform is up and running, we don't rule out continuing to collaborate with the chosen developer for ongoing maintenance and future development.
Required skills: full-stack development, searchable/filterable database design, robust authentication systems (with anti-credential-sharing mechanisms), user messaging/contact system, and prior experience with similar platforms (listings, B2B search, or subscription management).
To apply, please include:
Similar projects you've completed in the past
A separate quote for Phase 1 (Beta) and Phase 2 (full platform)
An estimated timeline for completing each phase
Client's questions:
Describe your recent experience with similar projects
We are looking for a highly experienced Computer Vision / AI developer or development team to build a scalable, on-premise employee attendance and workforce tracking platform** using NVIDIA DeepStream (preferred) or the Savant Framework. The solution will leverage CCTV camera feeds for face recognition, person re-identification (ReID), and multi-camera tracking to automate attendance, monitor employee movement across facilities, and detect when employees leave or return to their designated work zones.
The platform should include a modern, web-based Admin and Supervisor Dashboard that enables administrators to manage employee profiles, upload multiple face images per employee, configure unlimited cameras, buildings, and floor layouts, upload floor plans, position cameras on maps, define work zones (geofencing), and visualize employees' real-time locations on interactive 2D floor maps. The architecture should be modular, scalable, and suitable for deployment across multiple environments while supporting an unlimited number of users and cameras.
Applicants should have proven hands-on experience with NVIDIA DeepStream or Savan, multi-camera tracking, face recognition, person ReID, and full-stack dashboard development**. Please include examples of similar computer vision or AI surveillance projects you have successfully delivered.

This project is 12 months long with 5 phases. Can you commit to 12 months part-time? What's your availability to start immediately? Are you okay with stages and budget, can you suggest your questions or alterations? Are you a freelancer?
Phase 1 launches in 1.5 months (just login + UI/UX). We'll iterate fast with user feedback. Are you comfortable shipping imperfect code, getting feedback, and improving? Or do you prefer perfecting before launch?
Are you able to work with AI client AI linkage type products, CRM, Base44, UIUX Figma, PRD Development, DFD Development etc?
We're looking for an experienced Full-Stack Developer to build the Booking & Appointment Management module for our existing AI-powered SaaS platform.
Our platform, branding, core infrastructure, and product vision are already established. You can explore the existing platform and features on our website to understand the product before applying.
This project is not for building an entire SaaS product from scratch. Your responsibility will be to design and develop a production-ready booking module that integrates seamlessly with our existing system.
The module should include appointment scheduling, calendar management, staff availability, customer bookings, automated reminders, payment integration, and an owner dashboard for managing appointments and business operations.
The ideal developer should have strong experience with React or Next.js for the frontend, Node.js, NestJS, or Python (FastAPI) for the backend, and PostgreSQL or MongoDB for database design. Experience with REST APIs, role-based access control, authentication, payment gateways, WhatsApp/SMS notifications, cloud deployment, and scalable SaaS architecture is highly preferred.
If you've previously built booking systems, scheduling platforms, or SaaS modules that integrate into existing products, we'd love to hear from you.

I need a small, clean website that carries a modern look from the landing page through to the private dashboard. Visitors should be able to create an account, sign-in with email and password, then confirm access through two-factor authentication before they reach their personal area.
THIS MUST BE DONE WITHIN THE NEXT FEW HOURS
Once inside, the dashboard must show two things: a clear timeline of their account activity and their current subscription or membership status. There also has to be a section where each user can download PDF invoices that I upload from the back-end.
I’m comfortable with any lightweight stack—Laravel, Node, Django, or a well-structured WordPress plugin—so long as it stays fast, responsive, and secure. A simple admin panel where I can drag-drop or select new invoices and assign them to the right user is essential.
Deliverables
• Responsive, modern-branded front end (landing + login + dashboard)
• Secure authentication flow (email/password + 2FA)
• Dashboard modules: activity history, subscription details, downloadable invoices
• Admin interface for uploading and mapping invoices to users
• Source code and brief hand-off notes for future edits
I’ll consider the project complete when I can upload a test invoice, log in as a demo user, see their activity and subscription details, and successfully download that invoice without errors.

I need my Go HighLevel (GHL) account to talk directly with HeyGen so I can trigger automated video creation, voice cloning, and custom animations from inside my existing workflows. The scope is pure API integration—I already have keys for both platforms; I just need the calls wired up correctly and reliably.
Here’s what a finished job looks like for me:
• A contact event or pipeline move in GHL fires a webhook (or script) that hits the HeyGen API.
• The payload passes dynamic variables that control video type, cloned voice, and animation style.
• HeyGen returns the finished asset URL, which is captured back in GHL and attached to the contact record or pushed out via SMS/email.
Acceptance criteria:
• All three HeyGen functions (automated video, voice cloning, custom animations) can be triggered and verified from GHL.
• Code or webhook configurations are cleanly documented, with comments or a short README so I can extend the flow later.
• Any helper scripts use mainstream, maintainable tech—Python, Node.js, or native GHL webhooks are all fine—so long as the solution is stable.
That’s the whole brief. If you’re comfortable wiring up APIs and testing end-to-end flows, let’s pin down a start date.

We are looking for a developer to help review and complete an existing real-estate tokenization platform.
The project idea is to make real-estate investment more accessible by dividing property value into smaller digital shares. Users can invest in a portion of a property, track their holdings, and buy or sell their shares through the platform.
One of our team members will likely be unable to continue participating in the project due to a sudden accident. Therefore, we are looking to hire another developer immediately to help review, complete, and move the project forward.
The project already has a user web app, admin dashboard, and backend API. It includes identity verification, property management, payments, portfolio tracking, token minting, trading, and blockchain integration.
This is job overview.
📌 Overview
We are building a platform that makes real-estate investment more accessible by allowing property value to be divided into smaller digital shares. Instead of buying an entire property, users can invest in a smaller portion, track their holdings, and trade their shares with others. The platform is designed to connect property owners, investors, and administrators in one secure system. It includes identity verification, payment handling, ownership tracking, and a marketplace-style experience for buying and selling property shares. The main goal is to make real-estate ownership more flexible, liquid, and easier for more people to participate in.
🎯 Key Responsibilities
- Review the existing frontend, admin dashboard, and backend codebase.
- Identify completed, incomplete, and risky parts of the project.
- Improve and complete user-facing features such as sign-up, login, KYC, property browsing, portfolio, payments, and trading flows.
- Maintain and improve the admin dashboard for users, properties, KYC review, transactions, support, and settings.
- Work on backend APIs for authentication, user management, properties, payments, KYC, trading, and portfolio tracking.
- Integrate frontend and backend features smoothly.
- Fix bugs, improve code quality, and remove unstable or unfinished logic.
- Improve security, validation, error handling, and production readiness.
- Work with blockchain/Web3 developers to make sure token, wallet, and transaction data is correctly reflected in the app.
- Help prepare the project for deployment when ready.
📚 Required Skills
- Strong experience with React and modern frontend development.
- Strong experience with Node.js, Express, and TypeScript.
- Experience with MongoDB or similar database systems.
- Experience building REST APIs and integrating APIs with frontend apps.
- Experience with authentication, authorization, and secure user flows.
- Experience with payment systems such as Stripe.
- Good understanding of file uploads, email services, and third-party integrations.
- Ability to review an existing codebase and create a clear completion plan.
- Good communication and documentation skills.

Client's questions:
Describe your recent experience with similar projects
I need a working tool that continuously pulls event-level probabilities from Kalshi and Polymarket and contrasts them with real-time money-line, spread prices, over under prices and prop markets from major online sportsbooks. The goal is simple: highlight pre-game markets for Football, Basketball, Tennis, Soccer and Baseball where the implied probabilities diverge enough to create positive-expected-value opportunities.
Core workflow
• Fetch live or regularly refreshed odds via public or paid APIs (or reliable screen-scraping when an API is unavailable).
• Convert every price to a clean, comparable implied probability.
• Compare the Kalshi / Polymarket probabilities against each sportsbook’s line.
• Flag and log any gap that exceeds a configurable threshold, then push an alert (email, Slack or Telegram preferred—open to the best fit).
Technical preferences
Python is my default, but I am open to Node, Go or another language if you can justify speed or API compatibility gains. Please structure the code so the market modules (Kalshi, Polymarket, each sportsbook) can be swapped or extended easily. A lightweight web dashboard or CLI summary that lists the latest discrepancies would be ideal, though a Jupyter-style report is acceptable for a first milestone.
Acceptance criteria
1. At least one live feed each from Kalshi, Polymarket and two major sports books available in my area demonstrates automated parsing and probability conversion.
2. Alert fires when a test threshold is deliberately breached.
3. Documentation shows how to add a new sportsbook module in under 30 lines.
4. Code runs on a standard cloud instance without paid add-ons beyond the data sources themselves.
Let me know your proposed stack, data-source access strategy and estimated turnaround so we can lock in milestones quickly.

We are seeking an experienced developer to create a mobile app and CRM system for our business platform. The ideal candidate will have a strong background in mobile app development and CRM integration, with the ability to design and implement custom solutions. Responsibilities include developing user-friendly interfaces, integrating CRM systems, and ensuring seamless functionality across platforms. The project requires collaboration with our team to understand business needs and deliver a high-quality product.
## Project Overview
We're building a next-generation property management SaaS platform (V2) with a modern, event-driven architecture. The system is built around an event spine, per-domain row-level security policies, a trust/verification engine, and a financial/ledger layer. Core architecture and a significant portion of the migration plan are already in place — we're looking for an experienced developer to join, understand the existing system, and help carry it through to a finished, production-ready build.
This is not a greenfield "build whatever you want" project — you'll be working within an established architecture and extending it correctly, not redesigning it.
## Scope of Work
- Continue implementation across existing architectural layers (event spine, RLS policies, trust engine, financial layer)
- Build out remaining backend functionality on Supabase (Postgres, Auth, RLS, Edge Functions, Realtime)
- Develop and/or extend frontend features (React/Next.js)
- Design and secure API endpoints for multi-tenant SaaS usage
- Write and maintain automated tests; help establish/improve CI/CD
- Work from existing documentation and architecture decisions, flagging issues or risks as they come up
- Collaborate closely on financial/ledger-related features where correctness and auditability are critical
## Required Technical Skills
- PostgreSQL — advanced (functions, triggers, indexing, query optimization)
- Supabase — Auth, Row-Level Security (RLS) policies, Edge Functions, Realtime
- Event-driven / event-sourced architecture (event spine, CQRS, idempotency, replay handling)
- Multi-tenant SaaS architecture and data isolation patterns
- API design and security (REST or GraphQL, rate limiting, auth flows)
- React / Next.js
- TypeScript
- Financial/ledger system development — double-entry patterns, precision handling, audit trails, reconciliation
- Automated testing (unit, integration) and CI/CD pipeline setup
- Git workflow and code review discipline
## Strongly Preferred
- Experience shipping a SaaS product to production (not just feature work inside an existing codebase)
- Experience working with AI coding assistants (e.g. Claude Code) as part of a professional workflow, including critically evaluating AI-generated code rather than accepting it uncritically
- Security-conscious development, particularly around RLS-based access control and handling sensitive financial data
- Comfortable working from existing architecture documentation and extending it, rather than starting from scratch
## Soft Skills
- Strong written communication — able to explain technical tradeoffs clearly
- Self-directed; comfortable owning a feature or module end-to-end
- Responsive and reliable async communicator
## How to Apply
Please include:
1. Examples of production SaaS applications you've built or significantly contributed to (links if possible)
2. Your experience with Supabase and/or event-driven architectures specifically
3. Your approach to using AI coding tools in your workflow (if any)
4. Availability and estimated hours per week

We are seeking an expert Senior Flutter & Backend Architect to execute an urgent, comprehensive technical overhaul of our multi-vendor Click & Collect platform.
A recent technical audit identified significant vulnerabilities, native crash risks, state/architecture flaws, and cloud resource billing explosions. We need a senior engineer who can jump in immediately, clean up the codebase, implement production-grade security, fix critical native bugs, and refactor our core architecture.
*Timeline & Urgency:
This project must be fully completed, tested, and delivered within 15 days from project start. Only apply if you have immediate full-time availability and proven experience executing fast-paced refactoring sprints.
1. High-Priority Security & Payment Hardening:
-Secure Payment Flow: Re-architect Moyasar payment flow so order payment status (paid: true) and order creation are strictly verified server-side via Cloud Function webhooks, eliminating client-side status manipulation.
-Credentials & Keystore Management: Move hardcoded live API keys out of source code into dart-define / environment variables. Configure production release signing keystores and enable R8 bytecode obfuscation / shrinking in Android.
-Firestore Security Rules: Draft and deploy strict firestore.rules preventing unauthorized updates to fields like account_type, paid, and cost.
2. Native Platform & Crash Fixes:
-iOS Permission Manifests: Add missing NSCameraUsageDescription and NSPhotoLibraryUsageDescription keys in Info.plist to prevent native app crashes on image upload.
-Push Notifications (FCM/APNS): Fix cold launch token acquisition logic on iOS so APNS tokens are reliably fetched on boot.
-Display & Localization Fixes: Update iOS CFBundleDisplayName and localized strings.
3. Performance & Billing Optimization:
-Telemetry Throttling: Fix live driver GPS tracking write explosions by throttling Firestore writes from 15-meter intervals to 30–60 second intervals or buffered batches.
-Database Query Refactoring: Eliminate $N+1$ query patterns in catalog fetch calls (e.g., fetchRestaurantSummaries) by denormalizing essential root fields and implementing pagination.
-Asset Optimization: Convert and compress 50MB+ uncompressed image assets (e.g., raw 4K images) to optimized WebP formats to shrink bundle size and reduce startup RAM usage.
4. Architecture & Quality Refactoring:
-Type Safety & Models: Replace untyped Map String, dynamic parameters and raw string literals with strongly typed Dart models (using @freezed or Equatable) and enums.
-State Management & DI: Transition volatile RAM state to persistent local caching (e.g., Hive / SharedPreferences) and introduce proper dependency injection (e.g., get_it or Riverpod).
-Clean Up & Testing: Remove dead code/seed scripts from production binaries and set up a basic automated test suite (test/) covering core calculations.
*Required Skills & Qualifications:
-Flutter / Dart Expertise: 4+ years of deep experience building and refactoring complex, production-grade Flutter apps.
-Firebase Master: Hands-on experience with Firestore Security Rules, Cloud Functions (Node.js/TypeScript), FCM, APNS token lifecycle, and performance monitoring.
-Payment Gateways: Experience integrating webhook-verified payment gateways (Moyasar, Stripe, or similar).
-Native Android & iOS: Solid understanding of build.gradle.kts release signing/R8, Info.plist permission configurations, and native build troubleshooting.
-Clean Code & Architecture: Strong knowledge of Clean Architecture, SOLID principles, Dependency Injection, and modern state management (Riverpod, BLoC, or Provider).
-Availability: Immediate start with capacity to hit the 15-day deadline.
*Note for Applicants:
Please review the attached audit report PDF (ENTERPRISE TECHNICAL AUDIT REPORT) for the complete breakdown of identified issues, architecture deficiencies, and technical requirements before submitting your proposal.

# 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.”
