About Me

Who I Am

I am a highly motivated Java Full Stack Developer with a strong focus on backend development. I have hands-on experience building end-to-end web applications using Java and Spring Boot, following layered architecture and clean coding practices.

I have worked extensively on developing RESTful APIs, implementing JWT-based authentication, handling business logic in the service layer, and integrating relational databases using MySQL. I am also familiar with React.js and Thymeleaf for frontend integration to support backend functionality.

My technology stack includes Java, Spring Boot, REST APIs, React.js, MySQL, and I have consistently delivered projects with JWT authentication, Docker-based deployments, and role-based security layers.

I recently earned a Full Stack Java Developer certification from GUVI | HCL (An IITM Incubated Company), where I built industry-ready projects by following agile development methodology, clean code principles, and real-world problem-solving approaches.
