Performance Engineering Tech Lead / Architect

Responsibilities:

As a JEE performance engineering Tech Lead/Performance Architect at Confidential the responsibilities involves Confidential gathering, performance test strategy, workload modelling, code reviews, UI performance recommendations and performance test execution. Three different projects that are involved are Confidential, Safe and Early detection system (EDS). The responsibilities as a part of these projects involve the following activities. Confidential gathering by communicating with product owner and customers. The static code reviews and recommendations for UI tuning are shared with the development team. Based on the requirements the performance test strategy and work load modelling are derived. The depolyment of the build to the performance test environment. The performance tests are executed and the results are analyzed and shared with the team. This role also involves coordinating with the offshore team for performance test execution and giving technical inputs for performance test strategy and work load modelling. The capacity of the production servers is monitored as a part of capacity planning and the recommendations for capacity are shared on a monthly basis.

Performance Architect

Responsibilities:

As a Performance Architect in Confidential the responsibilities include UX prototype reviews, Architecture reviews, performance test reviews, failed customer experience(FCE) analysis and production support. The UX prototype reviews decide on which contents of a web page can be loaded before the others which has an impact on performance. Architecture reviews involve reviewing system/application architecture for performance, availability and resiliency. Performance assessment during development phase of a project includes profiling and UI analysis. Performance test reviews identify performance bottle necks during performance testing and recommendation for resolving these issues. This also includes profiling the applications that do not meet SLA. Production support involves working on live production issues, analysis of the performance issues and recommendation for resolving it. As a part of UI performance analysis, a tool chain was developed for monitoring, trending, alerting and optimization. This tool chain also includes WebPagetest private instance for synthetic monitoring. This role also involves giving technical directions to the team in offshore.
