    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.

    Well before the World Wide Web was a common phrase as it is today, before most people even owned a home computer I was programming code in a variety of languages for a variety of network related projects back when you had to put the handset of a telephone on a 300 baud modem. Trillions of lines of code under my belt and a mind that functions like a computer processing unit I not only understand today's most popular programming languages, I know how the languages themselves came to be. I am an expert who has owned, operated or worked with thousands of technology based businesses over the past 25 years. More than a programmer, I am a valuable consultant to any business wishing to build or improve any online enterprise. My work is relatively fast, accurate, functional and most importantly well constructed based on your exact needs. I do all of my own work but will bring in experts if necessary to accomplish the goals of your organization. I am an American living in Pennsylvania.
