Biography

Biography

Greetings!

With over a decade of cybersecurity experience under my belt, I bring skills from both offensive and defensive knowledge across a wide spectrum of domains.

Over the years, I have contributed to securing the ecosystem and uncovering vulnerabilities at platforms such as

  • Cantina
  • Sherlock (Senior Watson)
  • Secure3
  • Code4rena
  • The Saloon
  • Immunefi \

I've conducted more than 60 audits on various protocols, generating hundreds of findings.

Hacker's Mindset

I come armed with a hacker's mindset, dedicated to uncovering unique and hard-to-find vulnerabilities. My track record includes performing security reviews and identifying severe issues in prominent protocols like Optimism, GMX, GoGoPool, Rocketpool, Reserve, and more.
My focus is on high and medium findings however I shape my audits per the customer needs and requests to make sure they receive the product they paid for and their security posture significantly increases.

Past Findings and Rank

For a glimpse into my work, you can explore some examples of previous findings and find my aggregated rank across multiple platforms on Sherlock:
