I build agent infrastructure, operational automation, and research tooling with clear boundaries, evidence trails, and human control.
- Sandbar — Self-hosted agent computers with dedicated Linux workspaces, visible execution, human takeover, and API/MCP control.
- PAI Mobile — A mobile control plane for local AI workflows: durable sessions, scheduled operations, recovery, and permission-aware automation.
- Ralph — A private technical-research case study on validation, auditability, observability, and human-in-the-loop decision boundaries.
