• Create k6/JMeter load/regression suites; add CI perf gates.
• Profile CPU/memory/IO; fix hotspots via caching, pooling, batching, query tuning, algorithms.
• Implement timeouts/retries/circuit breakers; maintain perf runbooks; test failure modes safely.
• Reduce alert noise (thresholds, grouping, dedupe) with runbook links; improve MTTR/MTTD.
• Lead perf deep dives; manage perf-debt backlog & remediation sprints.
• Partner with Product on TTI/TBT/Web Vitals; report measurable wins.
• Full-stack support: ship features, review PRs with perf focus, mentor on instrumentation.
