About this gig

Built something with Cursor, Lovable, Bolt, v0 or Replit, and now it breaks in ways you can't explain?

AI writes code fast. It also leaves hardcoded API keys, broken auth, unindexed queries, zero error handling, and an architecture that collapses the moment you get real users. I clean that up.

WHAT YOU GET

- Audit report: what's broken, what's dangerous, what's just messy, ranked by severity

- Security fixes: exposed keys, missing auth checks, injection risks, open endpoints

- Refactor into a structure a human can actually maintain and extend

- Real error handling, logging and input validation

- Tests on the critical paths so it stops failing silently

WORKS WITH

React, Next.js, Angular, Node.js, Python, .NET/C#, TypeScript, SQL, Supabase, Firebase

WHY ME

- 6+ years in production codebases. Reading other people's code is my job

- I tell you what's genuinely risky vs what's fine, instead of inflating the scope

HOW IT WORKS

1. Send me your repo and what's going wrong

2. I do a free 10-minute scan and tell you which package you need

3. You order, I fix, you get clean code plus a written change summary

I'm a full-stack developer with 6+ years building production systems in healthcare, education and business management. I work across the whole stack — .NET, Python, Node.js, React, Angular, SQL Server, PostgreSQL — and handle everything from database design and architecture to deployment and monitoring. Whether you need a system built from scratch, a new feature, a bug fixed or a slow app made fast, I'll propose the approach that actually fits your needs.
