Second-year CS student in Hyderabad. I build retrieval systems, agents and the interfaces that make them usable — and I care about the parts you can’t see.

Understand the machinery. Build the system. Then make it useful.
I’m a second-year Computer Science student working at the intersection of software engineering and AI. Most of what I know came from building: chunking pipelines, embedding models, vector indexes, retrieval chains, FastAPI backends, LangGraph workflows.
I like taking an idea that sounds simple — “let’s make an AI that understands this” — and finding out what it actually takes to make it true. Build something, find the weak point, understand it, fix it. Repeat. That loop is the closest thing I have to a workflow.
