I will build or fix python fastapi flask and sql backend projects


About this gig
Are you dealing with Python backend bugs, broken APIs, or database issues?
I've spent a lot of time building and debugging Python backends, and I know how frustrating it gets when something just won't work. Whether it's a FastAPI route returning the wrong data, an SQL query that breaks under edge cases, or an authentication flow that's almost right but not quite, I can help you find the problem and fix it properly.
What I can help with:
Python bug fixing and code cleanup, FastAPI and Flask backend debugging, SQL database issues and query optimization, API integration and fixes, authentication and login system logic, CRUD backend development, and overall performance improvements.
Why work with me?
I focus on actually understanding your code before touching it. I don't just patch symptoms, I trace problems to their root cause and explain what went wrong so you're not stuck with the same issue later. My communication is clear, my fixes are clean, and I don't disappear mid project.
Before placing a large or complex order, please message me first. I like to understand the full picture before committing to a timeline, and it helps me give you a more accurate delivery estimate.
