I primarily enjoy working with Rails and Postgres or MongoDB, but I also enjoy JavaScript and front end code. I also dabble in graphic design. You can check out one of my flagship client http://www.kranichs.com -- which is Rails/Postgres and I did the UX/Design/Backend/CMS/Frontend/Ecommerce - basically everything! I have a knack for picking things up new technology quickly. I learned on PHP, and then found rails and haven't looked back since.
