    United States - Last active: 07/29/2014 - Tests: 10 - Portfolio: 20

    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

    Hi, My name is Aty. Over the last 7 years since 2007, I have led mufti-functional teams to execute on mission-critical engagements. I did job with large design firms in my starting career for 2-3 years. I then assembled a crack commando unit of the best people I encountered. We take on assignments, right-size the solution to the problem, and then use the team approach: an architect to ensure you have a platform suitable to your needs, razor sharp analysts to document the deliverable, creative designers for graphics, and masters of code. We then put very cheap SEO and maintenance folks to ensure your rankings remain at the top, and your site runs blazing fast. Each of these people bill at different rates, so you get maximum bang for your buck. When you hire anyone at Quinji, you hire the team resources. You will not suffer if someone is not available. We have the breadth of skills and depth of resources to ensure your project is on time and on budget. I am native US English speaker and this feedback is given to me by more than 20 different clients which they found a plus point while making conversation when they are outsourcing their work for better communication and understanding. Always available on Skype for voice or text during my working hours. I completed 2600+ hours on odesk with 4.96 star feedback out of 5 up to June 2014.
