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 the early part of my career. The last several years I've been in Capital Markets banking using Python, Java and Angular.
