I am a creative person who builds great software
I specialize in application scalability and performance, from small scale to large enterprise deployments. I turn buzzwords and acronyms into reliable production infrastructure. I'm deeply involved in open source, especially in the Ansible, Linux, Raspberry Pi, and Drupal communities.
I have a mildly popular YouTube channel and I write a lot (check out my books or my blog).
Please consider sponsoring my work.
