FastAPI services we deliver
Async REST APIs with Pydantic validation, dependency injection, and OpenAPI docs out of the box.
LLM proxy and gateway layers that emulate the Ollama/OpenAI APIs and route to free or paid models.

- Authentication (JWT/OAuth), role-based access control, and audit logging

- Docker packaging and Vercel/Render deployment
Why a Dhaka-based FastAPI developer
FastAPI is Python-native and pairs perfectly with the large Bangladeshi Python talent pool.
A single engineer owning backend + AI integration reduces handoff risk and speeds delivery.
How engagement works

Communication via GitHub, email, and WhatsApp; demos and docs delivered continuously.
