• Conducts scheduled and on-demand load, stress, and capacity tests and captures key performance indicators including percentile response times, transactions per second, CPU, memory, storage, and network utilization.
• Correlates performance data with application logs, infrastructure traces, and deployment events to identify bottlenecks, performance regressions, and configuration issues.
• Collaborates with development, operations, and security teams to validate fixes, refine test scenarios, and update performance baselines.
• Produces performance-test artifacts including automated test pipelines, KPI dashboards, performance summaries, and release-readiness inputs supporting operational resilience, mission assurance, and sustained program value across the War Data Platform (WDP) Core Integration ecosystem.
