• Verification of known issues and regressions.

● Use Login VSI (or similar performance testing tools) to:

• Create and run synthetic transactions to simulate user activity.
• Benchmark performance impacts of each release.
• Identify bottlenecks and areas for optimization.

● Monitor system performance and recommend tuning and optimization strategies for improved end-user experience.

● Collaborate with application teams, infrastructure teams, and IT support to resolve compatibility and performance issues.

● Investigate and document performance baselines and deviations post-release.

● Maintain detailed documentation for image build procedures, test plans, and performance metrics.

● Independently research and identify opportunities for system improvements and performance enhancements.

● Ensure compliance with enterprise security and change management policies.
