    My name is Alexander, or Sasha. I have 10+ years of commercial Java programming experience, using some popular Web frameworks. I dabbled in PHP and Drupal during my stay in London. Last 6 years, I was developing medium-sized enterprise Java systems using Spring, Hibernate and custom frameworks, using Agile processes, Git and Maven. My main points of interest are usability, rapid prototyping, reuse of existing frameworks as much as possible; and I would like to do more things for the cloud(s). I am learning Python and Google App Engine programming at the moment.
