IndiaWhat I'm looking for
I am a Java Full Stack Developer with hands-on experience designing and implementing RESTful APIs using Spring Boot and Hibernate. I have developed and verified 10+ REST APIs and executed 100+ CRUD operations in MySQL, focusing on clean, maintainable code and MVC architecture.
I improved backend performance by optimizing JPA and database queries, achieving up to 30% faster data retrieval during peak usage. I validated APIs with Postman, ensuring high reliability and successful responses.
My projects include a vaccination management system and e-banking features where I implemented secure authentication, transaction modules, and role-based functionality. I regularly use Git/GitHub for version control and follow best practices for scalable application development.
I bring strong communication, analytical problem-solving, and collaborative teamwork to every role, and I leverage tools like IntelliJ, Eclipse, VS Code, Maven, and AI-assisted development tools to improve efficiency and code quality.
