Romania - Last active: 9 days ago - Tests: 5 - Portfolio: 5

I graduated in Computer Science at Polytechnic University of Bucharest, Romania. I also have a masters degree in Advanced Computer Architectures. In 2012 I started my PhD. I have been working as a freelancer for 7 years now but I also had some regular jobs in the past as a software developer at some well known companies but decided to quit so I can only focus on freelance projects. I have experience with most programming languages, from C, C#, Java, C++ to Python, PHP, SQL, Javascript, Haskel, Clips. In the recent years I've mostly programmed PHP, Javascript and custom web applications. Frameworks I've worked with: Zend Framework, CodeIgniter, Django, Drupal, Wordpress, jQuery, Bootstrap, and any other PHP popular framework. I have two partners I work with on all projects, Mihail - developer and Petru - artist. I also have a lot of finished projects, websites I can show on request. Work Policy: * I try to deliver the best quality possible, but this is often a trade-off between time, budget, and the specific project situation. (For example, not all clients would want the time/money investment in creating a full unit test suite). I usually suggest a LAMP stack using either PHP or Python. * I'll be honest. For example, I like giving suggestions on how to save time/money even if that means less billed hours for me. I only work on hourly projects. Thanks!
