About

I'm a Software Engineer at TCS with a year of hands-on experience building backend services and full-stack applications using Java, Spring Boot, and Angular. My background is in Electronics Engineering — which means I think in systems, not just code. I understand how pieces connect, and I bring that thinking to every API and database I design. At TCS I've worked on Java, Spring Boot, Angular, REST APIs, SQL Server. Currently going deep on Java backend and microservices architecture. Always interested in problems that involve scale, clean design, and real engineering challenges.
