About this gig

Looking for a Python backend engineer who delivers production-ready APIs?


I build FastAPI REST APIs that are clean, fast, documented, and ready to connect to any frontend or mobile app. 5 years of Python backend experience APIs shipped for SaaS platforms, healthcare scheduling, and AI-powered applications in production.


What I deliver:

FastAPI REST API with full CRUD operations

PostgreSQL/SQLite database with SQLAlchemy ORM

JWT authentication and role-based access control

Pydantic schemas for input validation

Auto-generated Swagger/OpenAPI documentation

Docker setup for easy deployment

Clean, commented, error-handled code


Real projects I've built backends for:

- MeiChat: Multi-tenant AI chatbot SaaS platform

- GetOnCall: Healthcare scheduling and calendar API

- Fynite: Social platform with feeds and real-time notifications

- Amolino: AI revenue intelligence pipeline (OpenAI integration)


Message me with your requirements before ordering and I'll confirm delivery.
