    Australia - Tests: 2 - Portfolio: 2

    On the author list of bitcoinj project http://code.google.com/p/bitcoinj/source/browse/AUTHORS .

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.
