Founder and CTO of Helen’s Foundry.
Helen’s Foundry is the strategic-intent layer for AI agents. It connects company strategy, product decisions, implementation work, pull requests, and code in a temporal knowledge graph—then gives agents that context over MCP and checks whether what they ship still matches the decisions behind it.
I lead the core build: bitemporal graph architecture, verification systems, MCP integrations, and the infrastructure that turns strategic context into enforceable engineering signals.
I created googleworkspace/cli, a Rust CLI and MCP server for Google Workspace. Google fired me in April 2026.
Before that:
- Senior Developer Relations Engineer at Google
- Descartes Labs — petabyte-scale satellite imagery pipelines
- USGS — NASA-funded cropland mapping with machine learning
- Visual search over billions of aerial and satellite images — Computer Vision and Image Understanding, 2020
- Automated cropland mapping of continental Africa — ISPRS Journal, 2017
