À propos de ce service
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 5+ years building production SaaS end-to-end. I work with Svelte/SvelteKit and React on the frontend (with 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.
