    After graduating in computing, I spent a year developing interfaces and APIs for financial transaction devices in Windows before moving into an area that had more appeal for me : system level communications and messaging, largely focused on a C++ / Unix / Oracle platform. I spent six years mostly juggling messages and communication channels between databases and queues. But I got tired of living in big cities, and hatched an escape plan. I started doing short term contracts for web projects using a range of scripting languages at the server, and AJAX in the browserI began with various short term contracts for web interface development using content management systems and frameworks including Drupal, Django and Node, programming in languages including PHP, Python and Javascript/Coffeescript. I've moved on to building web apps with rich client side frameworks, often with a full javascript stack including mongodb.  less
