I’m a detail-oriented Software Engineering student with hands-on Java development experience and a growing foundation in Spring Boot, Hibernate/JPA, and Spring Security. I enjoy building backend systems with clean, layered architecture and role-based access that’s practical for real users.

In a recent remote frontend role, I built and maintained ReactJS features while keeping UI consistent across devices. I integrated and manually tested REST APIs using Postman to verify responses and edge cases, and used systematic testing to identify and resolve UI bugs.

My backend work includes a Dog Clinic Management System where I designed a multi-entity system (Owners, Dogs, Appointments, Veterinarians, User) with Spring Security RBAC. I optimized data retrieval by replacing default findAll() calls with custom @Query methods (LEFT JOIN FETCH) to eliminate N+1 query issues, and resolved LazyInitializationException by mapping entities to response DTOs at the controller layer.

I also build with strong engineering habits—validation and error handling, DAO–Service architecture, and reliable testing. From a Java JDBC CLI Food Management System to full-stack projects like a Next.js AI Job Portal and a MERN Doctor Appointment System, I aim to contribute production-minded design patterns and dependable software.
