Staff Engineer at Netflix

Building the engineering systems for an agentic software organization.

I lead technical strategy and build production platforms that enable large engineering organizations to move safely from AI-assisted development toward autonomous software engineering.

At Netflix, my work spans autonomous code change, deterministic validation and remediation, agent runtime infrastructure, observability, model access, policy and governance, and developer productivity. I was a founding member of the platform modernization team and have helped build systems that have shipped thousands of validated agent-driven pull requests.

Technical thesis

Build the system around the model.

Agentic software development is an engineering discipline: agents create leverage, but the surrounding architecture determines whether that leverage produces dependable outcomes.

AI is leverage, not magic.

The quality of agent work reflects the people, context, tools, and feedback around it.

Autonomy follows verifiability.

Increase authority when work is observable, testable, attributable, constrained, and reversible.

Own the control plane.

Keep enterprise context, policy, execution, and evidence under architectural control while models remain replaceable.

Raise the quality ceiling.

Cheaper implementation should buy better testing, modernization, and software—not just lower cost.

Leadership & impact

Technical authority is visible in the systems that other teams can use.

The common thread is not a particular model or framework. It is designing an engineering system in which higher autonomy produces more validated outcomes, better operational evidence, and durable leverage for the organization.

01

Autonomous software evolution

Production agent systems that take repetitive engineering work through governed execution, deterministic validation, remediation, and reviewable code change.

02

Enterprise agent platform

The shared operating substrate for agents: secure runtime, identity, tool governance, model access, telemetry, evaluation, cost attribution, and targeted controls.

03

Modernization that compounds

Platform abstractions and automation that turn difficult change into reusable organizational capability rather than a sequence of team-by-team projects.
