At Synechron, I developed and modernized backend services for HSBC's Supplementary Credit Card platform, supporting customer eligibility checks, onboarding, application processing, and card issuance. I helped deliver capabilities that supported onboarding approximately 120K users and led the migration from JDK 8 to JDK 17.

Previously, I developed backend services for Oracle Olympus Platform and Engage Plus at TerraPay India, including REST APIs for cross-border payments and partner operations. Across my work at Oracle, TerraPay India, Amdocs India, and Jio Platforms Limited, I've built Java and Spring applications and supported testing, performance optimization, and production troubleshooting.
