• Implement alerting strategies that reduce noise and focus on actionable signals.

• Lead incident response, conduct blameless postmortems and drive continuous improvement.

Enhance Developer Experience and Drive Platform Strategy

• Partner with application teams (platform customers) to understand their workflows and pain points, gather feedback, and prioritize improvements aligned with business objectives.

• Create and maintain documentation, runbooks, and knowledge bases that reduce knowledge silos and enable self-service.

• Drive decisions through written formats (RFCs, ADRs) that document architectural choices.

• Measure platform success through developer productivity metrics, adoption rates, and toil reduction.
