I will build your saas backend using fastapi and postgresql

I build reliable, production-ready backends for SaaS products using FastAPI and PostgreSQL the same stack powering real products like Stockline, a Shopify inventory demand-forecasting tool I developed end-to-end.

Every backend I build follows clean architecture: repository pattern for data access, Pydantic schemas for validation, proper error handling, and test coverage so you're not shipping guesswork. I containerize with Docker so your backend runs the same in development and production, and I structure the database with named volumes and settings management so it's easy to deploy and scale.

Whether you need a simple CRUD API for an MVP or a full backend with business logic like demand forecasting or analytics, I'll build it to be maintainable not just functional so you or your future dev team can build on top of it without headaches.
