Skills Required:

Proven experience in frontend and backend development.

Familiar with modern tech stacks (e.g., React, React Native, Flutter, Node.js, Firebase).

Comfortable with basic API integrations.

Interest or experience in basic AI integrations is a plus but not mandatory.

Ability to deliver clear and simple solutions, suitable for an early-stage MVP.

Hey! I'm building multiple apps using Cursor.ai and I’m looking for someone to help me finish them and create new ones.

You don’t need to be a pro developer—Cursor does 95% of the heavy lifting 😃. I just need someone with basic understanding of app structures and UI, who enjoys working with AI and putting things together.

I’ve already started two apps and don’t have time to finish them. You’ll get access to my Cursor.ai account and we’ll collaborate through chat, voice notes, and ClickUp.

My current budget is around $150 to $200 USD per month to start. The idea is to build a long-term, recurring partnership. If we work well together and you consistently help me finish and improve these apps, this can turn into something steady and bigger for a very long time. I’m looking for someone I can grow with—not just for one-time

TITLE: Developer Manager / Technical Lead (Part-Time) to Oversee AI-Powered Web App Development

YOU MUST SPEAK EXCELLENT - FLUENT, CLEAR ENGLISH! WE ARE BASED IN FLORIDA, USA.

ABOUT US:

We’re building a smart, scalable, subscription-based platform featuring AI-powered business coaching, downloadable templates, a Chrome Extension + Workspace Add-On, and full CRM integration. It's part of a larger project involving six (6) interconnected brands sharing the same infrastructure.

We are NOT building just websites — we are building a business ecosystem.

We need a Developer Manager / Technical Project Lead that works for us - not for the developers - to oversee all technical execution, review code, manage milestones, and ensure the final product is secure, scalable, and built to professional standards.

YOUR ROLE:

- Oversee the offshore development team (currently being hired)
- Help define deliverables and evaluate timelines
- Review all code for quality, bugs, security, and scalability
- Test Stripe, GPT-4, CRM, and other key integrations
- Track developer milestones and enforce quality sign-off
- Communicate status updates in plain English (not just code speak)
- Store all code securely in our GitHub repository
- Ensure developers deliver production-ready, secure, and complete builds
- Be the final approver before we release payments for any milestone

✅ REQUIRED SKILLS & EXPERIENCE:

- Past experience as a Lead Developer, SaaS CTO, or Technical PM
- Strong knowledge of JavaScript/React, Node or Python, PostgreSQL or Firebase
- Experience with OpenAI GPT-4, Stripe API, CRM (e.g. GoHighLevel)
- Familiarity with Chrome Extension or Google Workspace Add-On development
- Deep understanding of version control, dev environments, and QA processes
- Can speak fluently with both developers *and* non-technical stakeholders
- Can work on Eastern Standard Time (EST) hours at least part-time
- Strong security, testing, and deployment background is a must

🕒 TIME COMMITMENT:

- Part-time (10–20 hours/week)
- Ideally available for daily or near-daily check-ins during key milestones
- Will coordinate with an offshore development team across India, Pakistan, or Philippines

COMPENSATION:

- flat monthly rate negotiable
- Bonus structure possible after successful launch
- Potential for long-term relationship across multiple SaaS platforms

🚀 TO APPLY:

Please submit the following:
1. A short introduction of who you are and relevant experience
2. A list of recent SaaS or AI-related projects you’ve overseen
3. Description of your approach to QA, code storage, and milestone sign-off
4. Your availability in EST time zone
5. Your hourly rate or flat fee

FINAL NOTE:

This role is critical to the success of the platform! We don't need a "Yes Sir or Yes M'am" person. We want someone who protects the project from poor execution, missed red flags, or tech that’s held together with duct tape!

If that excites you, we want to work with you.

Let’s build something legendary, securely, and with excellence!

Website/dAPP
· Social media app with typical features (profile/avatar, following users, scrolling through others’ posts, etc.)

· Users post 1 meme per day for the contest

· Users are given 5 Likes/Votes to use on others’ memes. 1 vote per meme.

· Users should be able to click on something that tells them about the daily contest theme.

· Users scroll through others’ memes

· Connect TrustWallet and MetaMask wallets

· Register with wallet, email or phone. If they register without a wallet, they need to make a username and password.

· Users are not required to have a wallet. But, if they don’t, then I need a way to manage their rewards accumulation until they connect a wallet.

· Memes show the # of likes (the total count is not hidden until the end of the contest)

· Users should see the # of likes/votes they have used (and have left) per day

· Push notifications for 1) New daily contest theme, 2) Daily contest winner

· Advertisements in-app (ad-based revenue).

· Ensure users are real people (anti-bot). Don’t need full KYC, but I only want real people using the app.

· Cloud provider TBD, though I think you prefer Google.

· Images will be stored in cloud (unless you think IPFS is more practical), but I think you said Firebase.

· I’ll provide a list of hundreds of contest themes. Daily theme should be randomly selected, but I should have the ability to manually-override any day’s theme the night before. This list should be updateable somehow, ideally from a backend data source.

· Daily contest should be the same for all users (not generated client-side per-user)

· Content moderation should scan both text and images and auto-delete. Ideally, it should also allow me to see what was deleted (so I can monitor the effectiveness of the CM). No set preference yet on open-source vs. third-party service like Google Cloud Vision.

· English-only app for V1, but future will support other languages

· Users can earn rewards by referring friends that sign up



Mobile App
· Same as Website, but mobile-friendly (Android and iOS)



Admin App (Android only)
· View total Like count for the contest period (We burn this many tokens each day)

· View winning meme (We reward the winning user with tokens)

· View referrals

· Rewards distribution is manual (I get the winners from the metrics page and then send daily rewards).

· Button to send rewards to users with wallets

· Button to save rewards for users without wallets

· Button to burn tokens

· Button to send referral rewards to users with wallets

· Button to save referral rewards for users without wallets

· I want to control my private key on the Admin app (not committed to any VCS so that no other developers can get access to the wallet’s key).

· Review user-reported inappropriate content and be able to accept or delete it.

🧠 Project: Build Secure Custom AI Sales Assistant for Contract & Positioning Intelligence

We are seeking a skilled developer (or small team) to build a secure internal-use AI assistant for our sales organization. The goal is to enable sales reps to quickly access insights about our company’s service terms, pricing, and positioning—alongside competitor language—via a private AI interface.

This will be used exclusively by our internal team. It must be secure, scalable to 10–20 users, and admin-controlled. No public access or user-facing outputs of full documents should ever occur.

🔐 Project Scope
We’re looking for a developer to create an AI assistant that can:

Answer natural language questions like:

“How does our cancellation policy compare to [COMPETITOR NAME]?”

“Draft a follow-up email for a prospect concerned about pricing.”

“What’s the best way to explain our refundability clause?”

Pull insights from our contract documents, competitor terms, rebuttals, sales email templates, and positioning guides

Maintain tone and voice based on preloaded examples

Be accessed securely by authenticated internal users only

⚙️ Ideal Tech Stack (Flexible)
Layer Preferred Tools
LLM OpenAI GPT-4 API
Vector Store Pinecone, Weaviate, or ChromaDB
Middleware LangChain or LlamaIndex
Frontend Streamlit, Retool, or basic web UI
Auth Google OAuth, Firebase, or Auth0
Hosting Render, Cloud Run, or secure VPS
📁 Training Data (Provided by Us)
We will provide all training materials, including:

Company service agreements (PDF/Word)

Competitor contract examples (PDF)

Internal sales scripts and rebuttals (TXT/CSV)

Competitive positioning comparisons (DOC)

Email templates and pricing logic guides (Markdown)

Files will be well-organized for ingestion.

✅ Success Criteria
Agent can accurately respond to sales and contract-related queries

Language output aligns with our brand tone

No full-text output or download access to source documents

Admin user (non-technical) can upload, update, and manage training materials without dev assistance

Authentication required for all users

MVP is functional and testable within 3–4 weeks

🧑‍💻 Who You Are
You are a full-stack developer or AI engineer experienced with:

OpenAI API integrations

LangChain or LlamaIndex

Vector embeddings (Pinecone or equivalent)

Auth + secure web app development

Bonus if you’ve built Slack apps or Chrome extensions using LLMs.

💬 To Apply
Please include:

A brief overview of similar AI tools or agents you’ve built

Your recommended stack (if different from above)

Estimated timeline and total cost for MVP build

Any links to live tools or code samples

🟢 This is a high-impact internal tool for a fast-moving company. You’ll be working directly with the founder on a defined, well-scoped MVP. Long-term work possible if we expand this agent into other functions.

Active order transaction box button

This will be the transaction box that holds a slot once the shift request button has been pressed, a slot should appear in the box with a transaction status, similar to a transaction email, in an email box.

This is giving a user the opportunity to return the last page of the shift request that they left off on without completing the check out.

Once a transaction is completed through the shift request the slot in the transaction box should show as a completed transition and will still allow a user to click in to a receipt page.

The receipt page will be a separate smaller milestone after the transaction box has been set up.

We’re building a new web presence for G3 Inspection Solutions — an industrial QA/QC platform.

This project is to rebuild our landing page in React, based on a defined structure and branding direction. The current site is a temporary WordPress placeholder — we want a responsive, scalable React version that aligns with our product vision and can later expand into a full admin dashboard.

This is a trial project. If successful, we’ll continue working together on future phases: dashboard tools, report builders, Firebase integration, and admin functionality.



Project Details:
• Tech: React (Tailwind preferred), no WordPress
• Design: You’ll work from a written layout plan.
We don’t have a Figma for the website, but we do have a Figma file for the mobile app, which you’ll use as a style reference (dark theme, modern industrial UI)
• Theme: Clean, dark/silver UI — industrial, professional tone
• Hosting: Domain + Firebase already connected (project is live under our Firebase account)



You’ll Be Provided With:
• A full page structure/layout outline
• App Figma reference (includes branding and UI tone)
• Sample content and copy
• Link to the current placeholder site
• Admin credentials if needed (for teardown reference only)



Future Phases May Include:
• Admin login + role-based access
• Report/form builder tools
• Firebase authentication and data integration
• Project and inspection dashboards



To Apply:

Please include:
• 2–3 examples of React-based landing pages or dashboards you’ve built
• When you can start
• Whether you’re open to longer-term collaboration
Skills: React, Tailwind CSS, Responsive Design, Website Redesign, Java, Firebase

Assist in resolving any App Store Console errors preventing submission.

Confirm subscription access is gated correctly throughout the app.

🔧 Requirements:
5+ years of experience in React Native mobile development.

Deep understanding of StoreKit, react-native-iap, and sandbox vs. production testing.

Able to work independently, debug quickly, and communicate clearly.

📆 Timeline:

Project Overview:
We're a small electrical contracting business looking for a talented web developer to create a mobile-friendly, web-based app to manage 8-10 inspection audit forms. The app will allow our team of up to 10 electricians to log in, access form templates, fill out forms with photo uploads and digital signatures, and submit them as PDFs to Google Drive. It must be cost-effective, using our Google Workspace subscription, integrate with Simpro (via Zapier or manual export), and support Australian electrical standards (AS/NZS 3000). Minimal maintenance is key-no native iOS/Android apps due to update cycles.

Key Requirements:
Staff Login: Secure Google Workspace OAuth or email/password login for 10 users.

Form Templates: 8-10 audit forms (e.g., Electrical Panel Audit, Safety Check, RCD Testing) in a mobile-friendly dashboard.

Form Features: Text, checkboxes, dropdowns, photo uploads (1-5 images, 10 MB each), digital signatures, and basic logic (e.g., show actions if hazards noted).

PDF Submission: Convert forms to PDFs and save to Google Drive with email notifications.

Mobile-Friendly: Responsive for iOS/Android browsers (Chrome, Safari).

Integrations: Google Drive/Sheets for storage/export; Simpro via Zapier or manual upload.

Offline Workaround: Save form data locally (e.g., localStorage) if offline, re-upload when online.

Compliance: Support AS/NZS 3000 (e.g., grounding, RCD checks, timestamps).

Technical Details:

Host on free/low-cost platform (e.g., GitHub Pages, Firebase Hosting).

Use HTML, CSS, JavaScript (Bootstrap, jsPDF for PDFs; React/Vue optional).
Integrate Google Drive API and OAuth 2.0.

Ensure 2 hours/year maintenance (web-based, no app updates).

Deliverables:

Functional web app with 8-10 forms, hosted and tested.
Source code (GitHub repository).
Setup guide for Google Cloud/hosting.
User guide (1-2 pages).
1-hour Zoom handover.

Timeline: 3-4 weeks (start within 1 week).
Milestones:

30% (form design, auth).
40% (prototype with forms, PDFs).
30% (testing, handover).

Ideal Candidate:
Skilled in JavaScript, Google APIs (Drive, OAuth), and responsive design.

Experience building web apps for trades/compliance.
Familiar with Zapier/Simpro (a plus).
Fluent in English, available for Zoom calls.

To Apply: Submit a cover letter with your approach (e.g., Drive integration, offline workaround), links to similar web apps, proposed timeline, and budget (within $600-$1,200 AUD).
