Please peruse my GitHub profile for nearly all of my side projects. Notable highlights:
- a reimagined presentation of Isaac Asimov's The Last Question;
- the source code for my Next.js and React.js personal website;
- a single-serving numeronym generator app built using Serverless and AWS Lambda;
- my dotfiles and macOS configuration scripts;
- a Meteor.js and Three.js 3D online space flight simulation game.
I develop exclusively on macOS/UNIXlike operating systems, using git and modern tools.
I admin my own DigitalOcean server, but also deploy to Heroku, AWS Lambda, static websites, and other solutions depending on the need.
I spend a lot of time reading books, about half of the programming variety, half about personal finance. I love mentoring and teaching others to learn to code. I practice guitar, work on my old car, and travel as much as I can.
