    I've been in the web development field since 2002, when I started as a programmer/admin for a web hosting company. I've worked on a variety of web applications (generally php/MySQL based) ranging from ecommerce to in-house CMS to data mining/feed processing to integrating APIs and web services. I've worked with a number of PHP frameworks (Zend, CodeIgniter, CakePHP), and generally like working with a MVC design pattern. I've developed web applications from the ground up, as well as modified and added functionality to existing custom in-house systems, opensource applications, and commercial applications. I've worked with various APIs, including: Twilio, Twitter, Foursquare, Amazon, PayPal, Drop.io, Sunlight Labs, EmailYak, and others. I've written wrappers for APIs, as well as written APIs for outside integration into applications I've written. I am comfortable working with other developers and designers. In addition I've been asked to do code review and troubleshooting for projects where I had no active role. My profile on StackOverflow (http://stackoverflow.com/users/45531/tim-lytle) is a good sample of my ability to communicate the details of a development problem/solution. I'm also a Zend Certified Engineer (http://www.zend.com/store/education/certification/yellow-pages.php#show-ClientCandidateID=ZEND011439) with experience administering apache/mysql/php/etc on Linux (and a bit on Windows). Most of my oDesk clients are buyers who need high-level, conceptual requests to be understood and implemented, and the projects are ongoing long-term relationships.  less
