About this gig
Need a FastAPI backend built right? I'll deliver a clean, documented, production-ready Python API, not a tutorial scaffold.
I work with FastAPI day-to-day and know where it bites: async gotchas, Pydantic v2, SQLAlchemy sessions, JWT auth, and writing endpoints that hold up under real load.
What you get:
- FastAPI project structured for growth, not a single main.py
- PostgreSQL integration (SQLAlchemy)
- JWT or OAuth2 auth with refresh tokens
- Auto-generated OpenAPI docs at /docs
- Pydantic validation, error handling, CORS configured
- Clean source with README and requirements.txt
Good fits: SaaS REST APIs, auth systems with roles, CRUD with file upload, third-party integrations (Stripe, OpenAI, Twilio), LLM/RAG backends, webhook receivers, background tasks.
Stack: Python, FastAPI, Pydantic v2, SQLAlchemy 2.0, PostgreSQL, MongoDB, Redis, Celery, Docker. Also Go for performance-critical services on request.
Message me with what you're building, and I'll send scope, timeline, and an honest quote within a few hours.

I'm Tahmid, a full-stack developer with 6+ years of building production SaaS end-to-end. I work with Svelte/SvelteKit and React on the frontend (with a specialty in map and GIS interfaces), and FastAPI, Flask, and Node.js on the backend. I've shipped real apps for clients across retail, proptech, and B2B — including taajir.app (multi-branch POS), distrobooks.com (US wholesale), and propcloud.no (proptech, Norway, later acquired). I've also led infrastructure work using AWS, Terraform, Docker, and CI/CD pipelines in funded startup environments.
