Security Engineer · AI Security Researcher · Founder

I build things and think about what could go wrong. AI interests me both for the problems it helps solve and the new ones it creates. My work spans security engineering at Microsoft, product security at we45 and building Okynus Tech from scratch. I’m a generalist by approach. I like trying unfamiliar things, asking questions and working through problems without an obvious answer.

About

Practitioner. Researcher. Founder.

I work where AI meets real attack surface: finding how intelligent systems fail, and building what keeps them safe.

Today that’s at Vaatun. Before it came Microsoft and we45, and Okynus Tech, a security company I founded out of IIT Kanpur’s C3iHub and took to a ~$500K valuation.
