I will fix bugs in your django, fastapi or nextjs application
Ezequiel G
About this gig
Your app is broken and you need it fixed fast. I get it.
I specialize in diagnosing and resolving bugs in Python backends (Django, FastAPI) and Next.js frontends. No guessing, no wasted hours. I find the root cause and fix it properly.
WHAT I FIX:
500 errors, broken endpoints, database query issues
Authentication bugs (JWT, sessions, CORS)
Deployment issues (Docker, environment variables, server config)
Performance problems (slow queries, memory leaks)
Next.js build errors, hydration issues, API route problems
Integration bugs (third-party APIs, webhooks)
MY PROCESS:
1. Reproduce the bug in your environment
2. Identify root cause (not just the symptom)
3. Apply the fix + write a test to prevent regression
4. Deliver clean code with explanation
WHY CHOOSE ME:
10+ years debugging complex production systems
Worked on enterprise-level codebases (banking, education, insurance)
I communicate every step no radio silence
For urgent fixes: message me first and I'll confirm availability within the hour.

FAQ
Do I need to share all my code?
No. Just share the relevant files, the error message, and steps to reproduce. You can share via GitHub, ZIP, or paste directly.
What if you cannot fix the bug?
That is why I ask you to message me before ordering. I will review your issue first and confirm I can fix it. If I cannot, I will tell you honestly before you pay anything.
My bug involves multiple files, does that affect the price?
It depends on the complexity. Message me first and I will tell you which package fits. Simple bugs across a few files usually fall under Quick Fix.
