Turning Ideas into Robust Backend Systems

I'm a passionate Backend Developer with hands-on internship experience building production-ready REST APIs using Python and FastAPI, specialising in secure, scalable systems.

My expertise spans JWT/OAuth 2.0 authentication, multi-tenant architecture, PostgreSQL database design, and role-based access control — the building blocks of any modern API.
