I'm a 21-year-old software developer focused on backend development with Java and Spring Boot.

I enjoy building real-world applications and solving practical problems through software. My projects cover authentication and authorization, financial systems, dynamic search and filtering, REST APIs, database design, and full-stack development.

Through personal projects, I continuously improve my understanding of software architecture, clean code principles, object-oriented programming, and backend engineering best practices.

Currently looking for internship and junior opportunities where I can contribute, learn, and grow as a developer.
