• Automate manual and repetitive performance testing activities, treating test scripts, configuration and dashboards as code.
• Analyse application, infrastructure and database performance issues, find complex bottlenecks and drive tuning initiatives through completion.
• Build performance dashboards, prepare reports and provide evidence-based updates to technical and non-technical stakeholders.
• Manage test environments and test data, and make gaps between test and production environments visible.
