About

Founder, programmer, and cybersecurity competitor.

I build practical software at the intersection of AI, business, and cybersecurity. My main focus is B4Math, where I am building a decision-simulation product that turns company knowledge into structured, testable business scenarios.

Outside the startup, I compete in CTFs, build security tooling, enter hackathons, and work on civic-tech products. I care about systems that are technically credible, visually sharp, and useful beyond the demo.
