I started in QA and learned every stage of the pipeline. I understand how builds are made, and I fix what breaks.

When problems surface, I diagnose from first principles and solve with whatever tools the situation demands.

On Call of Duty that meant a 20–40-person engineering org (staffing that flexed with concurrent-title milestones) across six years of live-service delivery. When the target moved, we re-planned the trajectory and still landed close to what we’d committed. In 2023 I stepped away on a deliberate sabbatical to go deeper technically; now I’m ready to bring that back to a studio team.

(02) — In Practice

A live error was surfacing across Warzone and being worked as many separate problems: different symptoms, different owners, no shared cause. It was one problem, hotfixed the same day once the cause was found. What made it stay fixed is in the full report.

(03) — What I Do

What I do.

Senior production and technical leadership across the full pipeline, from greenlight to a shipped, stable build.

CAT/01

Production & Delivery

Run teams, schedules, and milestones to ship titles on time: pre-production through launch.

CAT/02

Program Management

Risk tracking, dependency mapping, incident response, and cross-team launch coordination that holds under pressure.

CAT/03

Pipeline & Tooling

Diagnose build, release, and live-ops pipeline problems from first principles and drive them to resolution.

CAT/04

Hands-on Delivery

When the situation demands it, I drive the build myself, directing tools, automation, and fixes through to shipped.

(05) — Let's talk

Bring me your hardest build.

The judgment to call what’s done, and the rigor to re-plan the trajectory when the target moves: six years of live-service Call of Duty, adjusting the plan without losing the commitment. That’s what I’d bring to your team.
