I’m a Python Backend Developer focused on building secure, production-ready REST APIs. I work with FastAPI and Flask to turn backend requirements into clean endpoints, reliable database interactions, and maintainable code.

In my projects, I’ve implemented JWT authentication and authorization, including role-based access where needed. I’ve built full CRUD flows with validation and clear database relationships using SQLAlchemy ORM with PostgreSQL and SQLite.

I enjoy shipping end-to-end features—from API design and dependency injection to testing and documentation. For example, I used Swagger UI for API testing and ensured endpoints were properly secured with JWT-based access control.

What excites me most is building backend systems that are practical and scalable, such as the Fitness Booking API and an E-Commerce backend. I’m also comfortable using Docker for deployment workflows and tools like Git, GitHub, and Postman to iterate quickly.
