    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
