    PHP Web App Developer: Any Framework, APIs and UI. 15+ years (USA)

    United States - Last active: 6 days ago - Tests: 6 - Portfolio: 12

    Since 1998 I have developed dozens of web applications focusing on a wide-range of industries including custom search engines, affiliate marketing, real estate solutions and worker safety. As an autodidact, I pride myself on learning new technologies and continually improving my skill-set. As a freelancer, I believe in professionalism, clean code and representing my craft to the highest degree possible. On the server-side, Laravel is my current PHP framework of choice, although I am comfortable working with Zend, CodeIgniter, Cake and Yii. For the database layer, I have 14 years of experience with MySQL. On the client-side, I prefer jQuery, Backbone and Twitter Bootstrap. Although I am not a graphic designer, I know my way around the Adobe software suite. I write standard compliant HTML5 and CSS3. I have an eye for useable, clean and obvious functionality. I have experience with many APIs, including Amazon, Box.net, Infusionsoft, Facebook, Twitter, PayPal, eWay, Authorize.net and Google. I can write APIs from scratch and give your application a RESTful interface. I am seeking opportunities to build custom web applications from the ground up or taking an existing code base and improving upon it.
