I have been programming since the early 1980s when I wrote my own word processor and many other packages for the Commodore 64, and I have been programming professionally for over 30 years. In my day job, I am a software architect for Appian where my primary focus is on internally-facing tools, developer infrastructure, and security. While software engineering has always been my main thing, I have also gone deep into system and network administration and other things in the IT domain, so my niche is really "infrastructure as code", which in important part of that nebulous thing people like to call devops.

I also maintain qpdf, an open source C++ library and command-line tool for working with PDF files. It started off as a closed-source package I wrote while at a previous job, but, with full support for my employer, I open sourced it, and nearly all my work on it has been as an open source project after leaving that company.

I am also an amateur musician and parent, which fills up most of the rest of my time.
