PROFESSIONAL EXPERIENCE

Confidential, Charlotte, NC

Responsibilities:

• Managed and applied CA/Hyperformix Capacity Management monitoring tools in a large enterprise production environment including current capacity monitoring and predictive modeling for Ecommerce/Online Banking, Banking Centers Call/Contact Centers, as well as mortgage, insurance, and infrastructure. Developed and managed automated monitoring using Hyperformix Data Manager to provide seamless input for both reporting and modeling tools: Capacity Command Center (CCC), Current Capacity Reporter (CCR), Capacity Manager (“CapMan”) and Performance Optimizer (Navigator).
• Developed numerous analytical and discrete event simulation models applied to application initiatives. The models cover the full Software Development Life Cycle: architectural design support, performance test analysis, as well as production capacity planning.
• Advised and aided in performance test and production triage situations and contributed to development of the monitoring and modeling planning.

Confidential,

Responsibilities:

• Lead modeler/analyst for new developing performance architecture team on-site at Confidential headquarters.
• Modeled and simulated a variety of computer systems from single servers to large multi-tier physical and virtual servers in initiatives targeting both existing and developing systems.
• Hyperformix Optimizer, Capacity manager and Data Manager were used in a variety of approaches from early architectural development models through performance test-driven models using LoadRunner performance test data. Using these forecast models, developed forecast projections requiring significant new hardware buildouts. Developed error analysis and provided confidence measures to qualify correctness of forecasts. Knowing “how well you measured” was well-received by the developing performance architecture team as an aid in communicating accuracy to business partners.
• Developed response time budget models as a member of the performance architecture team. These were combined with workload volumes in a newly-developing support environment targeting performance modeling for very large and complex systems. Identified long-running service calls and inconsistencies in response time reports to streamline and increase accuracy of new budget development processes.
