Agentic Engineering · Production Reliability

I install the discipline that makes AI agents reliable in production.

Rules-as-memory, parallel agent orchestration through git worktrees, adversarial review before every push, and grounding for user-facing agents. Anchored in seven years of shipping customer-facing software where downtime costs real money — the dashboard and account surfaces behind $200M+ in annual revenue at GoDaddy, and cloud infrastructure for nine-figure consulting engagements at PwC (via Kunai).

What I actually do

April 16, 20264 min read

The first time I watched an agent catch one of its own bugs — not because I told it to, but because an adversarial review step I'd wired up flagged the diff before it could push — I thought: this is what code review was supposed to be. Not…

Selected work

GoDaddy

Senior SDE · Growth & Account Experiences

Owned the experimentation framework for dashboard.godaddy.com — the primary surface for 20M+ customers — and the frontend reliability of the revenue surfaces behind it. The same instincts for rollout gates, experiment quality, and silent-failure detection are what make an agentic rollout actually safe to mandate across a team.

Kunai (PwC Network)

Senior Cloud Developer · Advisory Technology

Building developer experience and cloud tooling for consulting teams working under an AI-first mandate. Infrastructure-as-code, observability pipelines, and the agent-workflow discipline that keeps engagements shipping on a client clock instead of debugging their own tooling.

Meshify & Earlier

Full-stack · IoT & Data

End-to-end ownership from database to dashboard on IoT sensor platforms — legacy-to-React migrations, Go proxy services, and the kind of production workflow reliability work that teaches you which failures stay silent until a customer reports them.
