• As part of Epicentric’s professional services group, primarily responsible for performance testing and bottleneck identification/resolution for a number of Epicentric’s Fortune 500 clients who used Epicentric Foundation Server (a J2EE based web application framework) and a wide variety of operating systems, application servers, and databases• Utilized run-time analysis to observe discrete site elements (i.e. application server, database, operating system, network capacity) under load test. This analysis was a critical part of identifying and eliminating performance bottlenecks• Tuned the configuration of site components (i.e. application server, database, operating system, network capacity) under load for optimal performance• Used Silk Performer to create performance test scripts that would simulate a wide variety of complex and customized actions• Worked with an independent performance lab to certify multi-server Epicentric Foundation Server scalability• Interfaced with other members of the Epicentric engagement and engineering teams to facilitate custom code-reviews, support issues, research, and facilitate any client requests. Worked with clients to outline performance goals and initiatives. This involved interviewing business and technical personal, as well as reviewing log files and traffic reports for previous sites• Wrote compressive reports at the conclusion of each engagement. These reports included complete test results, site scalability estimates, configuration listings, test and issue summaries, as well as performance tuning recommendations• Maintained Epicentric’s Professional Services internal testing lab. This lab contains a number of servers and network appliances from different vendors in a controlled environment. This lab allowed Epicentric to import and test virtually any client site in-house, regardless of hardware and software used
