About this Gig
Your code is broken at 2am. You don't have time to figure out why. I do.
What I fix:
- Python (FastAPI, Flask, Django, data scripts)
- JavaScript / TypeScript (Node, Next.js, React)
- Performance issues (slow queries, N+1, memory leaks)
- Security smells (exposed keys, SQL injection, missing auth)
- AI / LLM apps niche specialty (RAG, prompt regressions, agent loops, OpenAI / LangChain / Claude API)
- AI-generated ("vibe-coded") apps fix what Cursor / Lovable / Bolt / Replit / v0 produced
Recent fixes:
- FastAPI websocket leak crashing at 200 concurrent users fixed in 2h
- Next.js hydration error blocking checkout solved in single delivery
- LangChain RAG returning irrelevant chunks root-caused to bad chunk overlap
What I deliver:
1. The fix (working code, tested locally)
2. Written explanation of WHY it broke
3. Recommendations to prevent recurrence
What I don't do:
- New features from scratch (separate gig)
- CSS / pixel-pushing
- Mobile native (iOS/Android)
- Production DB access (I work from logs/snippets)
Before ordering, share: the error or expected-vs-actual, the relevant code (paste or GitHub), ste

FAQ
I have proprietary code. Will you sign an NDA?
For Premium tier, yes — I sign Fiverr's standard NDA template at no extra cost. For Basic/Standard, the gig description acts as our NDA: I won't reuse your code or share it.
What if the bug is bigger than I described?
I'll quote a clear scope before starting work. If it's bigger, I'll send a custom offer with the upgraded price. You decide before any extra work begins.
My code uses OpenAI / Claude APIs. Can you debug AI-specific issues?
That's my specialty. Prompt issues, hallucinations, RAG retrieval failures, agent infinite loops, token cost analysis — I've debugged all of these in production.
Can you fix bugs in production code while it's live?
I can prepare and test the fix on my end. Deploying to your production is your call — I'll provide a clear deployment checklist with rollback steps.
Do you write tests?
Standard tier: I add tests for critical bug fix paths. Premium: I provide a test strategy report and add tests for all fixed issues.
How fast will you reply?
Usually within 1 hour during my waking hours, worst case 4 hours. I run automated message monitoring so nothing slips through overnight. First reply will quote scope clearly before any work starts — no surprise upsells mid-order.
