I worked on several impactful projects, including the Loan Origination System (LOS), Loan Collection System (LOC), Customer Relationship Management (CRM), and Lead Management System (LMS). In these projects, I leveraged Java, Spring Boot, Hibernate JPA, MySQL, and PostgreSQL to build and enhance features such as user authentication, API handling, and secure data management using Spring Security and JWT. I focused on optimizing the MVC architecture, integrating SMS and email notifications, and developing solutions for payment tracking and lead management. My role involved close collaboration with cross-functional teams, following best practices, and conducting thorough testing with JUnit and Mockito
