I will fix bugs in your python, fastapi, or backend API
Angel C
About this gig
Is your Python API throwing 500 errors? Are your FastAPI endpoints broken, or is your database refusing to connect?
Stop wasting hours trying to debug spaghetti code. I am a Principal Backend Architect specializing in Python, FastAPI, and robust server infrastructure. I don't just apply temporary patches; I find the root cause and fix your architecture so it doesn't break again.
What I can fix for you:
-API Bugs: FastAPI, Flask, and RESTful routing or logical errors.
-Database Issues: PostgreSQL connection drops, SQLAlchemy model errors, and broken Alembic migrations.
-Security Flaws: JWT authentication issues, CORS blocking your frontend, and Rate Limiting implementation.
-Deployment Errors: Docker and Docker Compose configuration bugs.
Why choose me? I build production-grade, scalable systems. You won't just get a working code; you will get clean, documented, and secure infrastructure.
Note: Please send me a quick message with your code or error logs before placing an order so we can evaluate the best approach for your specific bug. Place, thank you.

I specialize in backend architecture and system rescues. When APIs bottleneck or databases fail, I step in. As a backend engineer, my approach is surgical and methodical. I build robust systems one precise module at a time. I audit the core problem, restructure the architecture, and deliver secure, scalable code in record time. My technical stack is strictly focused on pure Python (FastAPI, SQLAlchemy, Pydantic) with OAuth2 JWT security integrations. I deliver modular schemas, Docker container environments, and clean logic for complex problems. Let's build your backend infrastructure reliably.
