Overview
A short maintenance engagement on an existing FastAPI backend for a client in Pakistan. The work focused on keeping the API reliable for the application and users that depend on it.
The Problem
Backends keep needing attention after launch: issues appear, code ages and small changes are needed. The client needed someone who could step into an existing FastAPI codebase and keep it running smoothly.
Solution
Worked inside the client’s existing FastAPI project, following its structure and conventions, and handled the maintenance tasks needed to keep the API stable.
