Scope#
Supported the core online services behind Call of Duty: Warzone 2.0 at Demonware (Activision). The work focused on production reliability, launch-scale readiness, observability, and operational response for high-traffic battle royale systems.
What I Owned#
- Service reliability for live player systems: Operated production services with emphasis on uptime, fault tolerance, and safe release behavior during live events.
- Capacity and launch readiness: Helped prepare infrastructure and service behavior for peak traffic windows and large launch demand.
- Automation and operational tooling: Built and improved deployment and infrastructure workflows to reduce manual operations and recurring failure modes.
- Observability and incident response: Monitored production signals, triaged incidents under load, and translated incident learnings into preventative platform improvements.
- Cross-team execution: Partnered with service owners and game teams to keep online experiences stable, performant, and shippable.
- Operational ownership: Participated in on-call and reinforced a service-ownership culture for live operations.
Reliability Outcomes#
- Improved operational readiness for launch and live-service demand through stronger reliability and capacity planning practices.
- Reduced repeat operational toil by increasing automation coverage in deployment and infrastructure workflows.
- Strengthened incident response posture with clearer production signals and tighter feedback loops from incident review to remediation.
- Increased resilience of customer-facing game services by prioritizing durable fixes over temporary recovery.
