I started learning computer programming with Ruby and Ruby on Rails in March 2013 in a Linux environment (Ubuntu, which is Debian-flavored Linux), so RoR is what I got the most open source project and in-depth training experience in. I am a full stack RoR developer very strong in BDD/TDD and Agile. Since then, I have branched out into JavaScript, Node, Magento, PHP, Angular, Backbone, and now F#. My work experience includes writing manifests, doing security patchwork, and programatically re-rasterizing image files and sanitizing infected databases and wesites. But oddly, PHP and JavaScript is what I got the most actual job opportunities for getting paid work experience in—even though I had to learn PHP and developing on the production server on the fly, which is strange considering that I did not start out learning computer programming in either .NET or PHP. My developer preference zone equally favors the functional (F# and Haskell) and OOP (Ruby/RoR) programming languages. I have a strong PaaS background and strong BDD/TDD capabilities, and a four year degree in mathematics. So I am primarily a full-stack Ruby on Rails software developer with a growing collection of successful PHP, JavaScript and F# closed source contract projects. So far, I have worked mostly with relational databases (MySQL, SQL, etc. etc.). I live in Erie County, Pennsylvania and I prefer remote positions but I am willing to commute to Buffalo or Cleveland. I am not available on-site full-time outside of this commuting area without upfront relocation assistance.
