Akash S
Informazioni su questo servizio
Is your FastAPI backend throwing errors, slow, or breaking in production? I will debug, fix, and improve it with clear updates.
What I fix:
API errors & 500/422 crashes
Slow endpoints & performance bottlenecks
PostgreSQL/SQLAlchemy query issues
JWT auth & login bugs
Validation & Pydantic errors
Broken deployments (Render/Railway/Docker)
You'll get: working code, a short summary of what was wrong and how I fixed it, and clean comments so you understand the fix (not just a patch).
Tech: Python, FastAPI, PostgreSQL, SQLAlchemy, Docker, Git
Send me your error message or repo access and I'll tell you honestly if I can fix it before you order.
