About this gig

Need a focused backend update for your existing Flask or FastAPI application?


I'm Frank Luo. My experience includes Python business applications, Flask services, FastAPI microservices, internal operations platforms and integrations between services.


I can develop or fix one small Flask or FastAPI backend feature, create or update one REST API endpoint, or integrate one simple documented API operation. Choose ONE framework and ONE task; we will agree on its acceptance criteria before ordering.


The Basic package requires an existing, runnable Flask or FastAPI project. It includes the changed source code and brief setup/test notes, plus one revision within the agreed scope.


It does not include a complete website, frontend redesign, payment integration, complex authentication, multiple integration flows, hosting fees or ongoing maintenance.


Please message me before ordering with the expected behavior, framework version and sanitized examples. Do not send production passwords, secret keys or private customer data.
