I will debug and optimize python backend fastapi django or flask queries

Your Python backend is broken and you don't have time to figure out why. Maybe a previous developer left you with a project that won't start, migrations that fail, or a 500 error you can't trace. I step in, read your code, find the actual root cause, and fix it no guessing, no rewrites you didn't ask for.

What I fix:

• Server won't start / crashes on boot
• Migration errors (Django ORM / Alembic)
• Broken serializers, views, routes (DRF, FastAPI, Flask)
• Dependency conflicts (requirements.txt, venv, Docker)
• Deployment failures (Gunicorn, Uvicorn, Docker, Render, Railway)
• Slow or hanging endpoints

How it works:

1. Send me your repo (GitHub/GitLab/zip) and describe the error.
2. I review it and confirm scope before you order (message me first for anything unusual).
3. I fix it, test it runs, and send you a short report of what was wrong and what I changed.

I work with Django, DRF, FastAPI, Flask, PostgreSQL, MySQL, SQLite, Docker.
