    I have a broad range of experience and an avid love for programming. My focus has been on back-end systems development. Lately I've been working primarily with PERL and Ruby, but I am very familiar with several other languages, such as LotusScript and JavaScript, and am quick to learn new ones. I've been using linux systems since 2000, so I am well versed with bash, sed, awk, etc.... You can see www.swajime.com for some samples of my work.  less

    Over the past 10 years I've developed software both professionally, and as a hobby. I enjoy working on more than just my daily grind, so I've come here for a little something extra. Do you have an interesting project? Read on, I may have the skills you need. Let's talk desktop/back-end development: C#, Ruby, Go, C, Objective-C, Powerbuilder, SQL (ANSI/MSSQL), Perl. Those aren't languages I've just spent a few hours on; I've shipped products or currently maintain projects in those languages. How about web development? I love writing responsive, cross-browser/cross-platform sites that work as well on the desktop as they do on your phone or tablet. It's a great challenge to stay ahead of the curve.  less

    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

    I am reliable. I can and have estimated dozens of web applications (sites) and delivered, or built, them as a full-stack developer and in a team as a lead developer and a team member. I am actively looking for oDesk contracts as of April 2014. My rate is 66/hour inclusive of oDesk fees. I have over fifteen years experience in full-stack web application development using Ruby on Rails, Grails, Groovy, Java, HTML5/CSS3, ATG, ILOG, Blaze Rules Engine, and cutting edge single page Javascript applications (AngularJS, Backbone,js, etc.). I have advanced JQuery experience. I have deployment experience on Heroku, Engine Yard, Amazon EC2 and other Amazon Web Services, and on custom server configurations. I actually get projects done on time and on budget. I am a veteran financial services system developer and architect. I was with Accenture for 8 years in their technical architecture skill track, in the financial services consulting group, and built numerous systems in finance, banking, and insurance. I worked on systems for JP Morgan, State Farm Insurance, American General Group, and many other financial service firms. I was a firm expert in transactional risk systems that performed real-time evaluation of risk and performed real-time risk decisioning. In 2007, I worked on Lehman Brothers automated mortgage underwriting system. Wasn't enough to save them from themselves (I have many good stories from that one!). Since 2007 I have owned my own development shop which has at times had up to three developers but as of this year is just made up of just myself. I am located in Oklahoma City and available for up to 25% travel. I have completed multiple full-lifecycle Ruby on Rails applications that I built and maintained over several years. I have developed other applications in Grails, HTML5/Javascript with JQuery and recently AngularJS. I have been developing cutting edge Javascript "one page" applications similar to Google applications (Maps, GMail, etc.) with responsive mobile first interfaces. I am not your typical oDesk developer and optionally work at client sites for a portion of my contracts to develop the necessary business knowledge.  less
