    Perry Butler

    Professional Freelance Software Contractor/Consultant

    United States - Last active: 06/30/2014 - Tests: 14 - Portfolio: 16

    Professional IT Manager and Programmer with over 12 years of experience in the industry leading two company's IT departments, with an expertise in web software development and design. Highly skilled conceptual programmer and software architect/engineer. I've produced many solutions from start to finish while being the sole programmer and project manager, including highly concurrent (multi-user) database systems that are in use today. My objective here on oDesk is to provide professional quality web programming and web design as an independent (freelance) contractor. As such, I deal with several clients/projects/employers throughout my average month and I enjoy this flexibility. I strive to produce results that are truly remarkable, some of which have never been seen before. This is an important driving force behind my work because you know you aren't getting a run-of-the mill design or a cookie-cutter solution when you hire me (unless that's what you want!). I'm not set in my ways and I don't adhere to one design pattern; every project is different and must be approached with a certain level of ingenuity. I prefer to build things from the ground up when unrestricted control over the design/layout/functionality is required. I am an expert when it comes to Wordpress development. I've designed many custom Wordpress themes from scratch including one fully AJAX theme (NO page loads), and two themes to power specific web apps. I've also built several custom Wordpress plugins from scratch and I have worked with other content management systems (CMS) such as Magento, Joomla, Drupal, MediaWiki and Dolphin; being familiar with several common platforms sheds more insight on the proper path/solution for the job. Proficiency with web languages and techniques: PHP, AJAX, HTML5, CSS, jQuery, ASP.NET, JavaScript, MySQL, etc. Proficiency with standard tools: Photoshop, Dreamweaver, Flash, etc. Proficiency with design principles: Responsive UI/UX, OOP, SEO, etc. Notepad++ and FileZilla are my tools.
