Spearheaded the Performance Engineering, High Availability, Scalability and Maintainability efforts across all end-to-end components of Comverse B/OSS Solution spanning IN-Centric and IT-Centric components/workloads. Worked closely with CTO and delivered a Highly Optimized and Cost Effective Solution that is currently being rolled out across several Tier-1 and Tier-2 Telecom Operators in Western-Europe and Asian countries and is being actively demonstrated to large North American Operators.

• Designed performance engineering scenarios and analyzed performance test results and logs. Worked extensively with cross functional teams (Development, Product Management, Services, Architecture and Business Analysts) to define traffic profiles and to isolate and fix major performance bottlenecks

• Defined task-level detail for various performance engineering projects, including effort estimates and resource allocation for test execution

• Assessed the network latency impact on system performance and user experience by utilizing hardware latency devices (PacketWare 2600E) to simulate user load across various geographical locations resulting in optimized hardware resource allocation across the globe

• Led Proof of Concept efforts to evaluate hardware vendors and technologies (such as IBM’s P-series high servers, IBM Blades, HP Blades, HP Itanium Servers etc.) and presented findings to senior management

• Significantly reduced the amount of time taken to collect various performance metrics by developing a suite of measurement collection scripts in Korn shell, Perl, awk and SQL.

• Developed a prototype of a regression model to predict server capacity, sizing and performance with a 95% level of significance

• Developed a suite of test scripts for webservices (SOAP) applications using Eclipse and JMeter.
