Senior software engineer. I build the architecture that lets AI-augmented teams move fast without breaking the rules that matter.
My contract-based governance framework runs in production on a high-throughput transaction platform that processes hundreds of millions of operations a day. It encodes business invariants into versioned contracts and binds them to the agent at the moment of the task, so AI-augmented work ships without a human re-reviewing every step. I operate this work through Substrate Systems, my software company.
Governance as compression: contracts and skills for AI-augmented codebases
The contract-and-skill pattern I shipped to production, and the controlled three-condition benchmark that showed the binding mechanism — not the documentation — is what moves outcomes.

The direct follow-up: why skill-triggered loading reliably outperforms bulk-context approaches — the cognitive distinction between retrieval and instruction-following that explains the benchmark gap.

Capture a Windows machine's apps and settings, then restore them on a fresh install. Local-first, with optional end-to-end encrypted backup. A shipped desktop product.
