At Tata Consultancy Services, I design, develop, and maintain RESTful APIs for enterprise banking applications using Java and Spring Framework.
On the InstaBIZ Mobile Banking Application, I developed core banking modules for Device Binding, Fund Transfer, and Forex Cards, and integrated the Google Play Integrity API to enhance application security.
I improved dashboard response time by 30% through performance optimization and root cause analysis. I also implemented Oracle database integration and secure transaction processing.
I write unit tests with JUnit and Mockito, investigate production incidents, and participate in code reviews. I’ve mentored three junior developers and collaborated with QA, Business Analysts, and Product Owners in Agile sprints.
