👋 About Me

Harshit Kumar

I'm Harshit Kumar, a 3rd year CSE student at IIIT Kota. I like building things that actually work — not just demos. Started with C++ and competitive programming, moved into backend dev, and now most of my time goes into Generative AI and Agentic AI systems.

I prefer understanding things properly before moving on — currently going deeper on DSA, Python fundamentals, and RAG pipelines.
