I am a Java Backend Developer passionate about building scalable, secure, and maintainable applications. I enjoy designing RESTful APIs, working with the Spring ecosystem, and solving real-world problems through clean and efficient code. I'm always exploring new backend technologies and continuously improving my software engineering skills.
These are some of my favorite technologies that I enjoy working with and use most frequently.
