Player profile
I'm now an old architect in a small piece of a very large company that bought us about twelve years ago. I've been into computers since grade school in the late '70s, and I still like building things end to end.
At work I'm focused on modernization. At home it's local LLMs, single-board computers, and recreating the games that got me hooked, built from their documented behavior and released for every platform I can reach.
