I am a Python Backend Developer with an intermediate English level (B1–B2), focused on building scalable, well-structured, and production-ready APIs using Django and Django REST Framework. I have hands-on experience with the complete software development lifecycle, from database design with PostgreSQL to containerization with Docker and cloud deployment on AWS. I am committed to writing clean, testable code and following industry best practices. In projects like the Scalable Management API and the News Scraper data pipeline, I designed secure authentication with JWT, automated unit tests with Pytest, and automated API documentation with Swagger UI. I enjoy collaborating with frontend teams to deliver robust backend services that scale.
