About this gig

Need a Python backend, an API, or a small web app that actually holds up in production? I build them in Flask and FastAPI.


I built and run a live Flask SaaS product myself: user accounts and teams, payments and webhooks, background jobs, file uploads, email, and a test suite of over 2,800 tests. That's the standard your project gets.


I can build:

  • REST APIs with clear endpoints and docs
  • Web apps with login, roles and an admin area
  • Databases (SQLite or PostgreSQL) and data models
  • Payment and webhook integrations
  • New features or fixes in an existing Flask or FastAPI app


You get the full source code, a setup guide, and an app you own outright. On the top package I launch it on your own hosting account.


Message me with what you need before ordering, and I'll suggest the right package and a timeline.

I’m a Python developer. I built and run a production web app that reads freight carrier invoice PDFs, checks every charge and flags duplicate bills. It has a Flask backend, background jobs, payments and over 2,800 automated tests. On Fiverr I help with: - Invoice and PDF data extraction to Excel or CSV - Fixing Python errors and bugs - Python automation for Excel and CSV work - Flask and FastAPI web apps and APIs I work entirely in writing: clear updates, written setup steps and quick replies, with no calls needed.
