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.
What you will see here at GitHub is primarily things I’ve written for myself: my development toolkit, some projects from graduate school, and a few side projects I’ve done just for the fun of it. Languages include C, Java, Python, Ruby, Perl, and Bash, along with some Go, PHP, and JavaScript.
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.
