Hey there

I am an independent developer and OSCP certified penetration tester. I focus on Ruby and Ruby on Rails development, and on penetration testing, code auditing and exploit development.
I usually help business to find security issues before the bad guys do to prevent any negative business impact.

I try to contribute to open source projects as much as I can. You can view all my contributions on my Github profile but here is a gist of them:


Send me an email or a twitter DM if you would like to reach me.
