Hi, I'm Sam!
I'm a software leader based in San Francisco. I build developer tools and scale engineering teams.
What I'm Working On
KS — An Attribute Grammar framework for TypeScript. Declarative computation over tree-structured data — define attributes and equations, the framework handles evaluation order, validation, and composition. Pure-data IR, two evaluation pipelines (lazy + compiled), and a self-hosted validator (the AG that validates other AGs is itself an AG).
