I am a Linux expert. I have been a linux user for 16 years and have used it professionally for 14 years. I was an early adopter of the Nginx web server and over the last 4 years I have been using it exclusively to manage high traffic web sites. I specialize in Linux security and have professional experience securing a web server using methods such-as but not limited to; chroot/jail environments, hardened kernel patches, and role-based access policies. I am an expert at tracking down even the most difficult of problems and most of my clients believe that I have a crystal ball under my desk. I am fluent in Python and PHP and can write everything from small scripts to automate tasks to a full blown command line application.
