I will turn your ai prototype into production ready code
Mateusz Trybula
About this gig
You built a prototype in Bolt, Lovable, or v0. It works. But it's not production-ready.
I fix that.
WHAT I DO
Audit the codebase (architecture, security, tech debt)
Refactor into clean, typed, maintainable code
Add error handling, logging, and input validation
Fix broken patterns, remove dead code, restructure modules
Deliver with commented code + handover documentation
TECH I WORK WITH
React, Next.js, React Native, Node.js, TypeScript, Supabase, PostgreSQL, Azure, Docker
WHY THIS MATTERS
AI prototyping tools skip the hard parts: scalability, security, observability, deployment readiness. I've been doing this for 5+ years. I know what breaks in production and how to prevent it.
NOT INCLUDED
New feature development, UI redesign, third-party API integrations not already in the codebase, infrastructure costs (hosting, domains, services).
Ready? Send me your repo link and a short brief on what the app is supposed to do.

FAQ
What do you need from me to start?
GitHub or GitLab repo access (or a zip file), a short description of what the app is supposed to do, and a list of must-have features. That's it.
Can you work with any framework or just React?
My primary stack is React, Next.js, React Native, and Node/TypeScript. If your prototype uses a different framework, message me first and I'll tell you honestly if I can help.
What if my prototype is very large?
Message me before ordering. I'll review the scope and send a custom offer with accurate pricing and timeline. I don't do fixed-price work on unknown scope.
