I have way more fun than one would think possible fiddling about with various Javascript libraries, either working on web applications for my day job at American Public Television, or developing a browser-based roguelike game. I've worked on ground-up responsive site redesigns & a newsletter management system in IBM Domino, written TV schedule fetcher agents in Java, developed CRUD interfaces and video judging web applications in AngularJS. I don't consider myself an expert, only a widely-exposed student.
