    John Johnson

    Sr. Software Developer

    United States - Last active: 2 months ago - Tests: 9

    I have been developing applications, specifically for the Windows platform, for over 15 years. I tend to do more web development and database development these days, but I have written my fair share of desktop applications and Windows services as well. I started out writing VB5/VB6 client/server applications while going to college. After a year or so, I made the switch to ASP & COM (web development). When .NET was released as Beta 1, I was lucky enough to be working for a company that let me spend some time doing a little R&D, and I haven't looked back. I am a guy that attempts to do find the "simplest" way of doing something. I find "over-engineering" an application to be a complete waste of time and resources. When coding, I try to assume that the next developer that will be working on the application will be a "junior" developer. This helps keep the code neat and simple; the architecture the same. I have worn many hats over the years, but tend to thrive when working as a contractor in a telecommute position. I love to work late. I drink a lot of coffee. And, I have a fairly nice home office setup. Thanks for reading. I hope to work with you in the future. - John

    Frontend developer with Backbone.js, Require.js (plus more) experience

    Romania - Last active: 05/23/2014 - Tests: 6

    I like to learn and keep my mind stimulated with interesting projects. I started with the LAMP stack up to the point i mastered Zend Framework. Then i moved on and worked a bit ( close to a year ) with MVC3, and now for a few years i'm back to one of my oldest passions. Frontend development technologies move so fast these days, they keep me busy learning every day. The stack i find myself working with more and more lately is formed by Backbone.js, Require.js, Node.js, Underscore, Handlebars ( tough i'm thinking of switching to dust.js ), jQuery and SCSS for styles, tough i've worked with many more and i'm constantly up to speed with the new frontend frameworks. I'm searching for a long term part time partnership, or projects up to 2-3 months.
