I started programming at the age of 8 on my Commodore Vic 20, and it's been my passion since. I love meaty technical challenges, but only if it solves a real world problem. Throughout my career I have been building high scale server-side web platforms, with particular focus in Knowledge Representation and Information Retrieval. As a committed agilist, I am passionate about Software Design and Architecture. Specialties: Horizontal scalability, Hadoop, NoSQL [Voldemort, MongoDB], Distributed enterprise and web platform architecture, Machine learning, RDF and Semantic Web technologies, Java, Ruby, C++ Dabbles in: Scala, F#, Erlang, functional programming in general
