Personal Profile

About Me

I'm a final-year Computer Science student building at the intersection of full-stack engineering, agentic AI, and cloud infrastructure.

Currently at Cognizant as a Programmer Analyst Intern, leading a team building a Bank Management System with Spring Boot microservices, Spring Cloud, and React. Before that, I worked at Wipro on API test automation for an enterprise cloud platform.

Outside of work I ship AI projects — a multi-modal RAG pipeline with OCR + vector search, an agentic e-commerce system backed by AWS S3, and a social graph app built for scale. I care about clean architecture, testable code, and things that actually work.

Side Hustle

Tech Rovers

When I'm not writing code, I'm making videos. Tech Rovers is my YouTube channel where I tackle everyday tech problems, share quick fixes, and post honest reviews of the tools and gadgets I actually use.

Think of it as the practical side of being a tech person — the stuff that doesn't make it into a résumé but matters just as much.
