I am working full stack and have recently used Java, Scala, Groovy, Akka, Play Framework, MongoDB, H2, Lucene, HTML, CSS, jQuery and Lighttpd.
My last projects were a search engine for classified ads and a platform for users to build their own web shops on. You can find my projects here <a href="http://sun.com.py/html/en/projects.html" >http://sun.com.py/html/en/projects.html</a> and most of my open source work here: <a href="https://bitbucket.org/parapapi" >https://bitbucket.org/parapapi</a>.
