I have 2 years of experience in Java development: creating server-side applications, working with distributed systems, microservices, network programming, analyzing big data, and implementing DevOps practices. I have always been motivated and a quick learner working in team projects. Although my main experience is in the backend, I strive to develop as a Junior Full-stack Developer and am actively studying front-end technologies (React, GraphQL) along with PHP/MySQL. Open to using modern tools such as AI and Copilot.
