crispycat's site

This site serves as a portfolio for my current and completed projects, including software programs and photography, and contains my weblog. I also operate other sites and services, collectively the Calitabby Network.

My interests include programming, network administration and cybersecurity, photo/videography, graphic design and 3D modeling, railfanning, engineering and architecture, and as well as various scientific and mathematic fields. I live in the Philadelphia area in the United States with my three cats who provide companionship, emotional support and "assistance" with various projects.

I do not participate in popular corporate social media and communication sites, but rather opt for free-as-in-freedom, decentralized services such as the Fediverse and Matrix, as well as my own websites.

I can be contacted either by email at or on matrix at You can also leave comments throughout the site using the form below.
