I'm Zac — a software engineer in Arlington, VA who builds things carefully and writes about it sometimes.

Currently building at Diana Health. Background in CS and machine learning with a focus on NLP. I care about craft, autonomy, and building things that last.

Here's what I'd show you first

LogARun Bot An automated training log bot that ran unattended for years. RNNs, AWS Lambda, and a good story.
On AI-Assisted Development LLMs are a tool, not a solution. A really, really good auto-complete.
Emergent Behavior Simulation Building in public — a civilization-style agent sim exploring emergent behavior.
