Experience
Senior Associate Technology L1
Jul 2025 — Present · Noida, IN
I have contributed to the modernisation of the LOS/LMS Monolith into microservices by owning a critical component of the Loan Origination stream. I rewrote the Eligibility Check Service (API) using Spring Boot (Java 21) and JPA, migrating business rules from the WebLogic-based legacy module. I have externalised environment configurations using AWS Parameter Store, ensuring secure and centralized configuration handling. I have deployed the service to a dedicated AWS EC2 development instance using SSH-based deployment for unit testing. I have created extensive test cases and performed unit testing to ensure stability ahead of SIT/UAT cycles. I have contributed to migration planning by analyzing legacy flows and identifying refactoring areas for service isolation.
