Selected Work

Production Agent Infrastructure

Designing and operating the infrastructure layer for autonomous AI agents at enterprise scale: control planes, secure runtimes, model gateways, cost attribution, evals, and policy enforcement. Side projects and adjacent interests are listed lower on the page.

Engineering

Agent Control Plane

The infrastructure layer for operating autonomous AI agents at enterprise scale.

Designing the infrastructure layer for operating autonomous AI agents at enterprise scale: identity, policy, telemetry, tool governance, runtime isolation, cost attribution, evals, and kill switches.

Engineering

Secure Agent Runtime

Sandboxed execution, least privilege, and bounded authority for production agents.

Secure execution infrastructure for production agents, with a focus on sandboxing, least privilege, runtime control, safe tool access, and bounded authority.

Engineering

Autonomous Software Evolution

Production agents shipping thousands of validated pull requests at Netflix scale.

Production agent systems that ship validated pull requests across large software ecosystems, turning repetitive engineering work into governed, measurable automation.

Engineering

AI Cost & Observability

Gateway-centered cost attribution and observability for agent workflows.

Gateway-centered observability and cost attribution for agent workflows: model calls, tool calls, session timelines, spend, outcomes, and failure modes.

Engineering

Platform Modernization

Turning organizational change into repeatable, measurable platform infrastructure.

Large-scale engineering systems for modernizing software platforms, reducing repetitive toil, and turning organizational change into repeatable infrastructure.
