I’m a Java Full Stack Developer who enjoys building reliable, production-grade web applications end-to-end. I work with Spring Boot and REST APIs on the backend, React.js on the frontend, and databases like MySQL and MongoDB to deliver features that users can actually use—especially around authentication, workflows, and real-time functionality. In my recent experience, I’ve contributed to multiple production applications covering modules such as vehicle listing, event creation, and auction management, and I also built and debugged a real-time bidding platform with OTP verification, email notifications, and CAPTCHA security integration. I’m comfortable integrating frontend and backend, using Git with Agile practices, and bringing structured MVC-based solutions from development through maintenance.
