During my tenure at Virtusa as a Software Engineer, I played a pivotal role in two key projects, notably the Phoenix project and the development of the "Cost Of Borrowing" web application. In the Phoenix project, I led the integration of the Broker Layout channel into BMO's banking system, streamlining loan processing procedures to enhance operational efficiency. Concurrently, I contributed to the "Cost Of Borrowing" application, which facilitated precise loan calculations and digital storage of mortgage information. Leveraging Java and Spring Boot, I designed and implemented REST APIs tailored to meet specific business requirements. Rigorous testing using tools like POSTMAN and SoapUI ensured the reliability and functionality of the APIs before deployment. Additionally, I managed code effectively using Git version control, addressing ad hoc tasks and bugs during testing phases. By optimizing SQL query structures, I improved application efficiency by 30%, resulting in a more responsive system. Furthermore, I prioritized code quality by writing JUnit tests for existing classes, enhancing code coverage and overall reliability. Through these contributions, I played a significant role in delivering dependable software solutions that met the evolving needs of the projects.
