Work
At TBS, I build biometric devices and the software around them. I own the web stack, ship mobile and desktop applications, and build the internal infrastructure that connects it all.
This site
Outside work, I build small products and experiments, follow whatever feels worth understanding, and write down what survives the process. This is where I keep those posts, project logs, and lists.
Now
Rebuilding this site and turning older notes into essays worth publishing.
