I’m a Java Full Stack Developer and MCA graduate, focused on building efficient, user-focused applications. I combine strong backend fundamentals with responsive frontend development to deliver scalable web experiences.

In my Full Stack Java Developer Intern role at EthonTech Academy, I developed full-stack web applications using Java, Spring Boot, MySQL, HTML, CSS, and JavaScript. I designed and integrated RESTful APIs, implemented backend logic, and optimized database operations using Spring Data JPA and Hibernate, while testing APIs with Postman and supporting debugging, deployment, and application maintenance.

Through my Behavior Analysis Using Deep Learning (Stress Detection Platform) project, I developed a web-based stress detection platform using deep learning models for stress-level classification. I trained and integrated prediction workflows using Python, Flask, PyTorch, and NumPy, then customized frontend components to connect seamlessly with backend services and database connectivity.

I also built full-stack applications like a Social Media Web Application and an E-Commerce Web Application using Angular, Spring Boot, REST APIs, and MySQL. I implemented features such as user authentication, profile management, post creation, product catalog, and add-to-cart, leveraging REST APIs to synchronize frontend and backend services while keeping development organized with Git/GitHub, Swagger/OpenAPI, and clear API testing with Postman.
