What I work on.

I'm a Developer Advocate focused on agentic coding — making coding agents genuinely useful for the people who use them, and writing down everything I learn along the way.

How I spend my time

01

Agent skills & Claude Code plugins

Packaging the context, tools, and guardrails that make a coding agent useful on day one — not day ten.

02

How coding agents actually think

Reading the traces, finding where agents get lost, and turning that into mental models developers can trust.

03

Developer activation

The unglamorous path from "installed" to "I get it now." Onboarding, docs, and that crucial first wow.
