I've been a professional developer since 1992, and started as a hobbyist back in 1982. As a hobbyist in the 80's and early 90's I worked with TRS80, Apollo, Dec, Apple II, Mac, PC's. Starting as a professional in the early 90's, I've worked with OS/2, Windows, and Linux, both on the web, client-server and multi-tier business applications, working mainly with Microsoft technologies through my career. I've been dabbling with Android lately (which has rekindled my hobbyist spirit!) I'm currently employed working on investment banking analytics.
