About
Who I Am
I'm a cybersecurity enthusiast and developer building secure systems — and breaking them to understand them better.
From participating in CTF competitions to building AI-powered security tools, I operate at the intersection of offensive thinking and defensive engineering. My work at Atlassian and leadership at FACT AMRITA shaped how I approach real-world security challenges.
Driven by curiosity. Grounded in practice. Always learning.
Currently Focused On
- AI-driven security tooling & threat modelling
- DNS infrastructure and secure networking
- Penetration testing and vulnerability research
- Open-source cybersecurity projects
