I will build and integrate a production grade python web app


About this gig
Your API needs to work correctly the first time, handle real traffic, and not fall apart when you add the next feature. That's the standard I build to 12 years of commercial Python, including HTTP API development and backend systems
What I can build for you:
- Web application in Django, Flask, or FastAPI
- Authentication: JWT, OAuth, SSO/SAML
- Database design and queries PostgreSQL, MySQL, MongoDB, Redis for caching
- Integration with third-party services
- Background/async jobs for anything that shouldn't block a request
- Clean, tested code with API documentation (OpenAPI/Swagger) not a script that only makes sense to me
I've designed backend architecture from scratch for a payment platform, led the team building it, and have supported production systems handling real customer traffic so I write code with an eye toward "what breaks this in six months," not just "does this pass the demo."
Tell me what you're building and I'll tell you honestly whether your scope fits Basic/Standard/Premium below, or needs a custom quote.

FAQ
Which frameworks do you work with?
Django, Flask, and FastAPI most often; Tornado if that's already your stack.
Can you work inside my existing codebase, not just build from scratch?
Yes — send access details in the requirements and I'll confirm fit before starting.
Do you also deploy the API to a server?
Deployment isn't in the core packages above but I do this regularly (CI/CD, Docker, Kubernetes) — message me for a custom quote if you need it bundled in.
Can you integrate with [Stripe/Shopify/some internal API]?
Certainly — list the service in your requirements and I'll confirm before you order.
