Work

Four live products I architect, and two engagements I can describe but not name.

Products, all live

Eve

Architect and primary author

A build kit for AI agents that survive a crash mid-task, stop at their budget and touch nothing without your approval.

Crash test

Spend
Capped, and broken down per agent and model

Vitrinka
