What I'm looking for

I seek a hands-on developer role where I can build and optimize APIs, work with Spring Boot/MySQL, collaborate in teams, and grow in backend and ML applications.

I am a Java Full Stack Developer with hands-on experience designing and implementing 10+ REST APIs using Spring Boot and ensuring data persistence with JPA and MySQL.

I have executed 100+ CRUD operations in MySQL, optimized JPA queries to improve backend performance, and validated APIs with Postman to minimize defects.

My skill set spans Java, Spring Boot, Hibernate, Python, frontend fundamentals (HTML, CSS, JavaScript), and tools like Git, Maven, and Eclipse, alongside strong communication and analytical problem-solving abilities.

I also have experience training students in AI and Machine Learning, leveraging practical labs and tools such as GitHub Copilot to improve development efficiency and code quality.
