Scope
#

Supported the core online services behind Call of Duty: Modern Warfare II at Demonware (Activision). The work focused on production reliability, launch-scale readiness, observability, and operational response for high-traffic multiplayer 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.

Tech Stack:

  • Languages: Python, C++, Golang, Bash
  • Infrastructure: Kubernetes, On-Prem
