Senior Java and PHP developer

Romania - Last active: 06/09/2014 - Tests: 5 - Portfolio: 1

I strive to achieve quality, correctness, performance and maintainability in the products I write. I believe a good understanding and application of software engineering principles is more valuable than familiarity with popular APIs or toolsets. In particular, this makes one flexible enough to handle any sort of programming task. My experience is as Java developer and web sites using PHP. I'm also doing Android projects. I also have excellent experience in: HTML, CSS, mySQL, XML, json

Nothing is impossible

United States - Last active: 10/04/2013 - Tests: 4

I am a computer genius with a degree in Software applications Programming and Development. I am currently working for a technology company full time, after being a contractor for them for a year. Honestly, I don't want to be sitting at a computer all day, but money talks. I will often look at job offers/invites, but I am not going to downgrade. The only jobs I would be interested in now are ones where I don't have to sit on my butt all day, and I would have to make more money.
