    Luke Jurgs

    Senior PHP/Javascript/SQL Developer

    Australia - Last active: 2 days 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.

    United States - Last active: 3 days ago - Tests: 2 - Portfolio: 2

    Over the past 10 years I've developed software both professionally, and as a hobby. I enjoy working on more than just my daily grind, so I've come here for a little something extra. Do you have an interesting project? Read on, I may have the skills you need. Let's talk desktop/back-end development: C#, Ruby, Go, C, Objective-C, Powerbuilder, SQL (ANSI/MSSQL), Perl. Those aren't languages I've just spent a few hours on; I've shipped products or currently maintain projects in those languages. How about web development? I love writing responsive, cross-browser/cross-platform sites that work as well on the desktop as they do on your phone or tablet. It's a great challenge to stay ahead of the curve.
