Measure, analyze, plan, and execute production-like simulations across mobile and web solutions to identify and remediate performance problems, prevent production outages, and guarantee predictable performance. Identify key technologies and architectures to creatively scale and improve code base performance, reduce resource consumption, and shorten request latency. Monitor application performance during performance tests or production usage using APM and other monitoring tools to isolate the fault domain, dive deep into application code, and identify root cause of performance issues. Monitor resource usage for physical servers, application servers and databases to drive optimization changes in production environment. Collaborate with development leads and project team to review and refine application NFRs, SLAs, & KPIs to create acceptance criteria and performance budgets necessary to measure, validate, and improve performance. Profile application performance from end-user perspective to inventory performance concerns and suggest tuning opportunities across the application stack. Interact with project teams, development, operations, and infrastructure resources to recommend solutions to remediate performance issues. Distill volumes of data, analyze performance results, diagnose performance problems, and clearly characterize system performance to stakeholders. Develop shift left performance practices, including execution of performance tests in Continuous Integration & Delivery pipeline. Execute end-user performance tests using selenium or similar automation tools to capture performance metrics on browser & mobile devices.
