I’m John Kerl, a software developer in the DC metro area. I’ve been hard at work in the software industry for 20+ years; 99% of what I do is intellectual property for the firms I’ve worked for. Most of my career in transaction processing, embedded systems, and data engineering simply isn’t visible here. My language strengths include C, Java, Groovy, and Ruby, with some Python; I’m currently most comfortable with Java and Ruby.
If you’d like to know more about what I do for a living, please feel free to contact me using any of the mechanisms to the left. Meanwhile, here’s a glimpse into some of the things I enjoy doing.
