I will debug and fix your python or fastapi backend
Krish
About this gig
I debug and fix Python and FastAPI code the crash that throws an error, and the worse kind: the bug that returns 200 OK with quietly wrong data.
What I've built:
- Two real, documented case studies: a shell-quoting bug that broke on file paths with spaces, and a silent float-rounding bug in a checkout endpoint that returned wrong totals with no error at all
- Every fix follows the same process: reproduce find root cause fix verify not guess-and-check
Clean delivered code with no clutter I explain the root cause separately so the fix itself stays readable.
Got a bug that's stuck, or code that behaves wrong but doesn't crash? Send me the error or the behavior and I'll tell you honestly if I can fix it and how long it'll take.

I build backend systems and automation tools, mostly Bash scripts, FastAPI services, and Python pipelines built to kill repetitive work.
Recent work: a full CRUD backend with FastAPI and PostgreSQL with proper validation and real session handling, plus an ML pipeline predicting gold and silver prices off 23 engineered features, running live with auto-retraining.
I also write Bash automation: backup scripts, a project-scaffolding CLI, background daemons. Small tools, real time saved.
Got backend work or repetitive tasks to automate? Let's talk.
