  Senior software QA team member for Cisco’s software system products used by companies in the satellite and cable TV broadcast industry. These headend products are high availability, complex multi-server software systems making use of Linux and Oracle. Responsibilities included developing test plans, automation tools and procedures for evaluating and verifying software performance to determine system throughput, capabilities, and scalability. • Analyzed system components to determine key areas in which to focus evaluation of system/sub-system performance. Designed performance tests using the appropriate simulation tools, such as JMeter, SoapUI, Spirent Avalanche, or worked with developers to create custom tools to simulate system activity. • Identified cause of API performance issues were due to the specific Java heap and garbage collection configuration, determined new configuration to increase software reliability and throughput. • Automated a previously manual procedure by developing web-based applications using JavaScript, HTML, Java, and Apache Servlets to automate the sending of requests to devices being tested. Later implemented a security layer, making use of AJAX and PHP, to control access to tool functionality. • Developed and maintained a website that organized and presented test information and results which allowed for a single, convenient, location for executive and engineer test data review and comparison. • Pioneered the use of Replay testing as a method to replicate customer system transactions in a lab in order to analyze system performance based on actual customer usage patterns, also proved to be extremely useful to investigate problems, and verify the performance impact of new software releases.
