    On the author list of bitcoinj project http://code.google.com/p/bitcoinj/source/browse/AUTHORS . However I did only contribute one patch, nonetheless this required reading c code and translating functionality into java. Worked with linux for 4 years, primarily Ubuntu. Eclipse is my primary Integrated Development Environment(IDE). Initially began programming with python, learnt a little bit of C++, including integration of python and C++. Unfortunately it has been at least 2 years since working with python and C++, so my knowledge of libraries and the languages has diminished. Currently spending a lot of time with Groovy and GRails. In the last two years programmed primarily in Java. Have experimented with github. Proficient in HTML5, CSS3, and javascript. Can read and write UML diagrams.

    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
