About this gig

FASTAPI BACKEND DEVELOPER | APIs That Scale, Perform, and Don't Break at 3am

A slow or buggy API kills your product. I build backends that don't.

FastAPI is the fastest Python web framework available, and I've made it my specialty. From simple CRUD APIs to complex microservices architectures serving ML models, I build backends that are fast by design, documented automatically, and architected to scale without expensive rewrites. If your mobile app, web app, or AI system needs a reliable data layer, I'm the developer you want behind it.

Services I Provide:

  •      RESTful CRUD API design and development
  •      JWT + OAuth2 authentication and authorization systems
  •     ️ PostgreSQL, MySQL, MongoDB, or SQLite database integration (SQLAlchemy/Tortoise ORM)
  •      File uploads, S3/Cloudflare R2 storage integration
  •     ️ Background tasks, Celery + Redis job queues
  •      WebSocket real-time endpoints

Not sure what you need?

Send me your frontend's requirements, existing schema, or just a description of your project and I'll design the API architecture in my reply.
