• Optimize caching strategies, including TTLs, refresh patterns, cache placement, performance, and management of downstream dependencies.

• Advance platforms towards active-active resiliency and validate scenarios for failure, recovery, and capacity.

• Design and implement automated CI/CD pipelines with rolling, blue/green, or canary deployment strategies, including automated checks and quality gates.

• Establish practices for infrastructure, configuration, secrets, and application deployment utilizing an everything-as-code approach.

• Create performance and load-testing capabilities along with performance gates for software releases.

• Develop monitoring, alerting, and observability for latency, throughput, availability, errors, and reliability metrics.

• Define and enhance SLIs, SLOs, error budgets, and operational KPIs.

• Automate operational tasks through scripting, tooling, and infrastructure automation.

• Diagnose production issues, conduct root-cause analysis, and lead blameless post-incident reviews.

• Offer technical guidance and engineering standards for SRE and development teams.
