Design, script, execute, and report performance tests (load, stress, endurance, scalability) across high-volume ordering, kiosk, POS, loyalty, and payment flows; Establish baselines, workload models, and SLO/SLI-aligned KPIs. Integrate AI-assisted workflows into performance planning, test-design acceleration, and results triage with human review; Maintain AI-consumable artifacts (NFRs, workload models, baselines, thresholds) and define guardrails for safe, policy-compliant AI use.
