Backend & API Development Services

MuchiTec builds backends and APIs with Python (FastAPI, Django) and Node.js (Express), and on managed platforms like Supabase and Firebase. Every backend ships with authentication, a clean database design, API documentation and the structure to scale as usage grows.

What's included

Secure, well-documented APIs and backends built with FastAPI, Django and Express - or on Supabase and Firebase when a managed backend gets you to market faster.

  • REST APIs with FastAPI, Django REST Framework or Express
  • Supabase and Firebase backends: auth, database, storage, functions
  • PostgreSQL and MongoDB database design
  • Authentication, roles, permissions and audit logs
  • Payment, email, SMS and third-party integrations
  • API documentation, testing and monitoring

How we approach it

Pick the simplest backend that will still hold up later. Supabase or Firebase for speed when the domain is straightforward; FastAPI, Django or Express when you need custom business logic, complex data or heavy integrations - often combined, with a clear migration path between them.

FAQ

Backend & API Development FAQ

Common questions about our backend development service.

  • Supabase or Firebase are great for launching fast with standard auth, data and storage needs. A custom FastAPI, Django or Express backend is better for complex business rules, heavy integrations or strict data control. Many products start on one and grow into the other.
