PHP5 years experience
Almost all of my professional work was at companies that used PHP, starting from my first part-time job in college up to my second-most-recent full-time job.
Lately, I have been specializing in front-end development, especially with React. I really enjoy working with it, but I'm very experienced with other things as well...
Ruby on Rails1 year experience
My current side project is written in Rails, and I have a good amount of experience helping people with their Rails projects (namely programming bootcamp students).
