Available for work - immediate start

I find infrastructure
exposures
before attackers do.

Over 500 security vulnerabilities found, documented, and responsibly disclosed to some of the world's most recognised companies. More than 300 rewarded. CEH V13 certified. In 2018, I discovered and disclosed an unsecured database exposing 2M+ records from mSpy - covered by TechCrunch and KrebsOnSecurity alongside Brian Krebs. That was not a one-off - since then, 100+ similar exposures found and closed. I do not just find problems - I give the teams who need to fix them everything they need to do so.

My story
Before security was a career,
it was just curiosity.

I was a computer science student more interested in how systems break than in what textbooks said about them. In 2016, before I even graduated, I sent my first security report to SitiBroadband - a vulnerability that gave unlimited free broadband access. No bounty, no reward. Just the right thing to do.

I graduated in 2017. By that point I had already been doing security research for two years alongside my studies - not because anyone asked me to, but because I could not stop noticing the gaps.

Then on 16 January 2018, I reported a cookie injection vulnerability to Redbus. They paid me a bounty - my first. A real flaw in a product used by millions of people, handled honestly. That moment set the direction for everything that followed.

Since then - over 500 disclosures, more than 300 rewarded, across companies of every size. The work is always the same: find something real, document it properly, report it honestly.
