    Alexandra DeWit

    Full-Stack Developer with Ruby/Rails experience

    Sweden - Last active: 16 days ago - Tests: 4 - Portfolio: 1

    For the last year I have worked on a number of web-based projects from start to finish. These have uncluded a mortgage brokerage's web application, a RESTful API authenticated through OAuth2 in order to provided ordering and purchasing capability, and the web client that utilizes it. I've also done a number of personal projects just for fun, including a fully functional chess game that supports the full chess ruleset, move history, game state saving and restoring( with history preserved ), and more. The bulk of my professional experience has involved ruby, rails, and various javascript frameworks, but I feel equally comfortable working with Java, C#, and a number of other languages. I strive to maintain the attitude that I can work with any language or framework, as long as some degree of documentation or sourcecode exists with which to start.
