Vice President of Engineering · Arcadia

Engineering leader who helped build CareJourney from employee #7 through acquisition — now running 48 engineers at Arcadia while building agentic-AI products on the side.

Currently VPE at Arcadia (48 engineers) · Building Cortex, an ambient agentic-AI cognitive substrate, in production.

I joined CareJourney as employee #7, built the production data platform, and led engineering through its acquisition by Arcadia in July 2024. Now I run a 48-person org while solo-shipping production agentic-AI systems — Cortex (cognitive substrate), Consul (EA), and Groundwork (civic field-ops). I've been building with LLMs since ChatGPT launched; agent-first ever since.
