The honest version. The guy on the other side.

There's no grand origin story here. Somewhere in second year I looked around, saw how easy it was to coast through college, and realised that scared me more than failing ever did. So I went at the two things that intimidated me the most: AI and LLMs in general, and security, breaking the things people assume are safe.

Before tech I actually wanted the Indian Army. Cleared the Service Selection Board, All India Rank 83. Five days with people whose entire job is figuring out who you really are. I ended up not joining, but those five days rewired how I work. Show up, do the reps, no excuses.

Everything else is pretty simple: coffee, David Goggins podcasts, and posting whatever I'm building or breaking on X. Including the failures. Especially the failures, honestly, because the OOM crashes and NCCL hangs taught me more than anything that worked first try.

Here's the part the other mode won't tell you: I got into security because breaking something honestly is the fastest way to actually understand it. Second year, everyone around me was suddenly trusting AI with everything, and almost nobody was asking how it fails. That question stuck. It still hasn't let go.

Before any of this I wanted the Indian Army. Cleared the Service Selection Board, All India Rank 83. Five days with assessors whose entire job is finding the gap between who you say you are and who you actually are. I didn't join, but that's more or less what I do to software now: find the gap between what it claims and what it does.

The rest: coffee, Goggins podcasts, and hunting on HackerOne and Bugcrowd at hours I won't defend. The Yatra chatbot XSS started as 'let me just poke it once before bed'. It usually starts like that.

Right now that means one thing: getting VantaLLM to a released base model. Right now that means one thing: finding the holes in AI systems before someone worse does.

What I work with. What I carry.

Don't code? Hover (or tap) any of these. Each one tells you what it is in normal words, then shows you exactly where I used it. Full list lives in the arsenal. Every tool here has drawn real findings, none of it is résumé decoration. Hover one and it tells you what it does and where it's been fired. Full kit in the arsenal.

IoT Lab, KIIT.
My people.

Every college has societies. IoT Lab is the one I gave two years to, first as a cybersecurity member, then as Lab Coordinator running the whole thing. 30+ members, CTFs, showcase days, onboarding juniors who reminded me of me when I started.

My tenure wrapped up in August 2026 and the juniors run it now, which was always the plan. These are still the people who were there before anything worked. They saw the failed demos, the 3am debugging, the events that almost fell apart and didn't. Family is the only word that fits.
