I will debug and fix your claude code or ai built web app
Alexander L
About this gig
Built your app with Claude Code, Cursor, Copilot or another AI tool and now it is stuck on a bug it cannot fix? I debug and stabilize AI-built apps.
Typical problems I fix:
- Login/auth failures (Firebase, Auth0, sessions, tokens)
- API calls that return errors or the wrong data
- Features that work locally but break when deployed
- Database and environment-variable problems
- Frontend bugs in React/Next.js, backend bugs in Node.js/Python
- Messy code that needs a safe, minimal fix and a few tests
HOW IT WORKS
1. You send a sanitized copy of the project (no secrets), your stack, the error and steps to reproduce.
2. I reproduce the bug, fix the root cause (not just the symptom) and add tests where it makes sense.
3. You get the fixed code plus a plain-English change log.
I work on code you own or have a license to modify. I never need production secrets; use test keys.
NOT INCLUDED: full rebuilds, open-ended new features, or guaranteed production launches. Message me first if the job is large and I will quote it.

I'm an automation developer and Navy veteran (9 years), CompTIA Security+ certified. I run a live SaaS product with paying customers, The Cleaners Place, built on Stripe billing, webhooks and authentication.
I fix broken n8n, Make.com and Zapier workflows, bugs in apps built with Claude Code or other AI tools, Stripe checkout, subscription and webhook issues, and messy Excel/CSV data.
I reproduce the problem, fix it, test it and send a written summary. I never need your passwords. Message me your error and I'll tell you honestly if I can fix it.
