Backend first. AI next.

Building reliable systems for banking, government and enterprise teams at TCS.

I'm a Java Backend Developer who cares about fast APIs, clean data and zero-downtime releases.

For the last 2.5+ years at Tata Consultancy Services, I've built and maintained enterprise applications across banking, government and resource-management domains, using Java, Spring Boot, REST APIs, PostgreSQL, Hibernate/JPA and Angular.

Now I'm expanding into Python, FastAPI, Generative AI, LLMs, RAG pipelines and AI agents, with a live project in progress — while pursuing an MBA at Manipal University Jaipur.
