Project details
Is your AI-built app 80–90% complete but not production-ready?
If you’ve built most of your product with AI tools yet feel stuck before launch, I step in as a full stack developer react node specialist and experienced full stack software engineer to turn your prototype into a stable, scalable product.
Whether your solution is a full stack react js application powered by node.js backend architecture or another modern stack, I audit your existing codebase, uncover architectural weaknesses, edge cases, performance bottlenecks, and security gaps. As a senior full stack web developer with production experience, I create a clear, prioritized roadmap outlining what must be fixed, improved, or finalized to ship confidently.
What I do:
• Audit AI-generated code and system structure
• Identify blockers and scalability risks
• Create a focused completion strategy
• Fix key issues or guide implementation
• Support deployment and launch decisions
Ideal if your app mostly works but needs senior-level direction to cross the last mile smoothly.

Foundation Website with Charity and Career, Mall, Authentication
Muhammad understands instructions well, and the first version of the website he created was almost stunning. One constructive suggestion would be to follow all instructions carefully and ask questions whenever anything is unclear. With his strong capabilities, Muhammad is well suited to handling complex projects and has great potential to thrive.

Build a CS2 Skill-Based 5v5 Matchmaking & Cash Pool Platform (Website + Backend)
Maaz did an excellent job on our gaming platform project. He understood the requirements clearly, communicated well throughout the process, and delivered quality work with good attention to detail. The project involved gaming-related functionality, UI/UX improvements, and technical implementation, and Maaz handled everything professionally.
He was responsive, open to feedback, and always tried to find solutions instead of just completing tasks mechanically. I especially appreciated his patience during revisions and his ability to adapt as the project evolved.
Overall, I’m very satisfied with the work and would definitely recommend Maaz to anyone looking for a reliable developer for gaming, web, or platform-related projects. I would be happy to work with him again in the future.

Job Success
Karachi, Pakistan - 3:17 am local time
Most teams don't need a rebuild. They need someone who can drop into a live codebase, ship an AI feature that holds up under real users, and hand it back clean. That's the work I do.
What clients say about that work:
▸ RAG chatbot with memory and recall, shipped into a live product; "Maaz is the badass of Full Stack development and a GPT Bot wizard. He owns his issues, bugs, and solves them like a Boss."
▸ GPT-powered SMS interface, built end-to-end; "Maaz gets it done. Clear communication, no excuses. Committed, reliable, and honest."
▸ CS2 skill-based 5v5 matchmaking platform; "Understood the requirements clearly, communicated well throughout, and delivered quality work with strong attention to detail."
Top Rated on Upwork, 100% Job Success across 9 completed projects.
How I work:
▸ I read your codebase before I quote. No copy-paste proposals.
▸ I ship in small, reviewable PRs, not month-long black boxes.
▸ I write evals alongside every AI feature, so you can trust what it does in production.
▸ When AI is the wrong answer, I'll tell you before you spend on it.
▸ I cap my active clients so your project stays in focus.
My stack:
▸ Frontend: Next.js, React, TypeScript
▸ Backend: Node.js, NestJS, REST & GraphQL
▸ AI: OpenAI API, LangChain, RAG pipelines, vector stores, agent workflows, N8N, BullMQ
▸ Data: PostgreSQL, Supabase, schema design, query optimization
▸ Cloud: AWS (EC2, S3, Lambda), Docker, CI/CD
Industries i have worked with as a full stack developer:
▸ Logistics & Supply Chain
▸ Fintech & Crypto
▸ Health & Wellness
▸ Food & Restaurant Management
▸ Real Estate
▸ Social Media
▸ Education & E-Learning
My expertise as a Mobile App Developer
I build production-ready apps with react native (as a react native developer / react native full stack developer) and can deliver via flutter full stack developer workflows when it fits.
Best fit if you have:
▸ A working Next.js or React/ React native product and want to add an AI feature properly
▸ A stalled AI build that needs someone to jump in and finish it
▸ An AI idea, and you want a straight answer on whether it's worth shipping
If you're weighing whether an AI feature is even worth building, I'm happy to jump on a short call and give you a straight answer, no pitch.
