I'm kind of a jack-of-all-trades guy.
Website and Mobile Development
I've been building websites since I was in 5th grade. I have experience in just about every aspect of building websites (including graphic design, copywriting, and search engine optimization). I've worked with PHP (CodeIgniter, CakePHP), Java (Spring framework), C# (MVC 2/3/4 framework), Ruby (Ruby on Rails, Sinatra), Python, and Node.js. Database experience includes MySQL, Oracle, and PostgreSQL. I've worked with a bunch of CMS like WordPress, Django, and Joomla; I even build my own called Basileus.
Custom WordPress Development (Templates, Plugins, etc.)
I've designed and built websites professionally for nearly 15 years and most of that time has been spent working on the front end of the website.
I bring up personal training because it's become a hobby of mine. Enough people have approached me that I'm comfortable calling myself a personal trainer even though I haven't been certified yet.
If you're interested, I built a fitness tracking application called Dexstr.
