    PHP Web App Developer: Any Framework, APIs and UI. 15+ years (USA)

    United States - Last active: 1 day ago - Tests: 6 - Portfolio: 12

    Since 1998 I have developed dozens of web applications focusing on a wide-range of industries including custom search engines, affiliate marketing, real estate solutions and worker safety. As an autodidact, I pride myself on learning new technologies and continually improving my skill-set. As a freelancer, I believe in professionalism, clean code and representing my craft to the highest degree possible. On the server-side, Laravel is my current PHP framework of choice, although I am comfortable working with Zend, CodeIgniter, Cake and Yii. For the database layer, I have 14 years of experience with MySQL. On the client-side, I prefer jQuery, Backbone and Twitter Bootstrap. Although I am not a graphic designer, I know my way around the Adobe software suite. I write standard compliant HTML5 and CSS3. I have an eye for useable, clean and obvious functionality. I have experience with many APIs, including Amazon, Box.net, Infusionsoft, Facebook, Twitter, PayPal, eWay, Authorize.net and Google. I can write APIs from scratch and give your application a RESTful interface. I am seeking opportunities to build custom web applications from the ground up or taking an existing code base and improving upon it.

    Senior PHP/Javascript/SQL Developer

    Australia - Last active: 1 day ago - Tests: 5 - Portfolio: 3

    Over the last 12 years I've worked with PHP, MySQL/PostgreSQL/MSSQL, JavaScript, HTML/CSS and related web technologies to create a large number of websites and web applications. I've worked for a number of startups and for a large listed company. My strength is the knowledge I have of what the web application stack is capable of, how interacts with the underlying server software/hardware and browser. This insight allows me to build robust, sophisticated and fast software. Most recently I have been building thick client side applications using Backbone.js and Require.js. I believe that the future of consumer software is going to be dominated by this type of software stack. It gives me great pleasure to be building the future right now. I also have excellent Ubuntu/Debian/CentOS Linux administration skills and have managed a large number of different servers. If you're after a serious and capable programmer then look no further.
