    I started programming computers when I was eight years old, and, over the last 30 years, I've realized that I am, well, a programmer. That said, I do have the "people skills" necessary to remain competitive in the world of programming. When needed, I'm a "sit in the corner and program til the wee hours of the morning geek"... otherwise, I'm just a "fun to talk to, easy to get along with normal person". I have always enjoyed the challenge of creating interactive software. With the birth of the modern Internet, I found a new love in web development and web programming. I face every new piece of code as a fresh new beginning... a chance to do it even better, while, still using "what works" from the past. My objective, here at oDesk, it to provide potential employers with my expertise in the field of website design, development, and programming. My skill include, in no particular order: PHP MySQL HTML/HTML5 CSS/CSS3 JavaScript jQuery AJAX Big Data Laravel WordPress Magento CodeIgniter Zend Python PhpDocumenter (PHPDOC) XMPP, OpenFire Google Places API Angular.js Revive Adserver OpenX Adserver OpenX REST API Revive XMLRPC API BitBucket Web Scraping C# ASP.NET Classic ASP MSSQL Twitter API Facebook API Google API Google Maps API Google AdSense API Backbone.js Smarty MS Access Linux Apache nginx PHP Data Objects (PHP: PDO) MailChimp, MailChimp API Google GeoCode API MongoDB LAMP LEMP Ember.js IIS Photoshop Flash ActionScript Intuit Quickbooks API Mint API Twitter Bootstrap cPanel Plesk Authorize.net Stripe PayPal Google Checkout BASIC RackSpace API (OpenStack, OpenCloud, etc.) SalesForce / SalesForce API TinyMCE Yoast SEO MailGun / MailGun API JIRA Confluence  less
