EdOverflow

I am a web designer, developer, security researcher, and have experience triaging for numerous vulnerability disclosure programs. In my spare time, I enjoy swimming, photography, cinematography, and playing the guitar.

In 2017, I published an Internet Draft for a proposed standard which allows websites to define security policies called security.txt. A year later, I created Bug Bounty Guide, a launchpad for bug bounty programs and bug bounty hunters.
