I will build a secure multitenant fastapi backend with jwt and postgresql

I build secure backend APIs with FastAPI JWT authentication, role-based access control, and PostgreSQL, not just a login page bolted onto a CRUD app.

What I've built:

- A multi-tenant backend with JWT access + refresh tokens, admin/employee role enforcement, tenant isolation on every query, and Alembic-managed database migrations

- Server-enforced business rules not just "logged in or not," but who can do what to which resource

- Rate-limited login endpoint, consistent error responses, Docker Compose deployment

I write every line by hand and test it against a real running database, not just code that looks right. Every rule I claim is enforced, I can show you the request that proves it.

Need authentication, role-based permissions, or a backend that's actually production-shaped? Send me your requirements and I'll be honest about scope and timeline.
