    Learn through data analysis, would be the tag line for me. I am a data scientist with business intelligence and text analysis background. I am also a JAVA/php/javascript developer, like databases, have a PhD (if important). Strong incentive to build systems that analyse and learn from data. I've done this for the last 8 years in academia and industry, and will try to do it for a long time (still only 30).
