I build AI-native tools, agent systems, and developer workflows.
My current focus is on making software agents more structured, observable, and useful in real engineering work: harnesses, multi-agent coordination, browser/runtime automation, writing tools, and knowledge workflows.
I care about tools that make thinking, writing, coding, and agent collaboration more controllable.
