    Wordpress / CSS / PHP / MySQL / JavaScript - Web Engineer

    United States - Last active: 8 days ago - Tests: 7 - Portfolio: 1

    I specialize in both front-end and back-end web development. I strictly follow design principles to deliver high quality product: 100% W3C compliance, DRY (Don't Repeat Yourself), responsive cross-browser compatible code, object encapsulation and unit testing. I believe good client-developer communication is key to success. I have 5 years professional experience - 3 years programming advanced laser manufacturing systems, and 2 years as a freelancer. I started programming as a hobbyist when I was 14 years old. As I operate several of my own high-volume websites, I know how important it is for clients to meet critical deadlines and get the job done right.

    Voice Over Talent / Audio Engineer

    United States - Last active: 1 day ago - Tests: 6 - Portfolio: 42

    I am a trained and versatile voice actor with almost ten years' experience in the industry. I've worked on commercials, apps, audiobooks, documentaries, eLearning modules, and video game characters. I have a background in theater, and received my B.A. in English Composition in 2008. As a full-time freelancer, I am extremely deadline-driven. Almost all smaller projects can be completed in less than 24 hours. I record on top-quality equipment in a professional studio, free of any background noise and custom built to enhance the warm low and mid tones of my baritone voice. I use Adobe Audition CC for all post-production tasks--editing, mastering, mixing, and sound effects; adhering to the broadcast standards, as well as those of ACX and Audible. I was born in America to British parents and am consequentially able to perform a multitude of accents from either side of the ocean. Character demos can be found in my Upwork portfolio.

    Sencha Ext JS 5.1 / Sencha Touch Expert

    Thailand - Last active: 1 day ago - Tests: 2 - Portfolio: 4

    The last 5 years of my career I have worked with products of Sencha (Sencha Cmd, Sencha Touch 2.3, Sencha Charts, Ext JS 3.4, Ext JS 4.2, Ext JS 5.x). I was fortunate to work with highly diversified range of tasks. The list includes: - upgrades of applications (Ext JS 3.4 -> Ext JS 4.x -> Ext JS 5.0), - mobile application development (Android, iOS, Sencha Touch), - using Sencha Charts, - integration of third-party libraries into Sencha products (OpenLayers, Highcharts, jQuery, Google Maps, Yandex Maps), - code testing in Selenium, Siesta, Sinon, YUI 2, - refactoring, - fully project reimplementation (rewrite a project from scratch, rewrite a project from JS to CoffeeScript), - consultations, - and much more. Javascript is one of the few languages that gives too much room for creativity, a space to express their thoughts. And unfortunately too easy to go far from the correct direction, from the decision to be easy to understand for other developers. That is why I firmly believe in the need to using hard coding standards and official recommendations. It's not important tha you are using for yours projects - PHP, RubyOnRails, C#, Ajax, XML, JSON, bla-bla... I just said you: Yes, I can do it! It's OK! I know well Git, worked with Subversion, used many task trackers: Jira, Redmine, YouTrack, and others, can't remember all.. Also my expirience included development of a mobile apps using Java for Android. If you need in one of the best, you're welcome!
