On the internet I go by the handle kiyell.

I have a background in IT support and software development but I’ve been a full-time bug bounty hunter since 2018. I enjoy pentesting web applications, mobile apps, and creating tools that that test for security vulnerabilities at scale.

Some of my latest endeavors have involved creating bash scripts that detect bug bounty scope changes, managing my Linux config files with Git, and using Jekyll & Github Pages to create the website you are viewing now.

I invite you to browse through my articles where I write about software development, security, astronomy, and other topics I am passionate about.
