About

Senior Product Engineer at Mindstone, working on Rebel, a local-first AI desktop app for agents that know your work, use your tools, and ask before doing anything risky. I focus on onboarding, product experience, character/brand systems, and making agentic AI feel understandable, useful, and safe for real teams.

Mindstone Rebel - AI workspace for agents that know your work and ask first

Rebel is a desktop AI workspace for agentic work. It connects your memory, meetings, files, actions, automations, and tools so AI agents can help with real work — while keeping sensitive actions behind approval checks. Built Fair Source, with portable workflows and model choice.
