About
I'm a Senior Manager with 25+ years across enterprise software development, mainframe product engineering, and the insurance vertical — with deep domain expertise in Life Insurance, Annuities, and Health Insurance.
My technical work centers on mainframe enterprise product development and modernization: building REST API–based web apps that bring legacy applications forward, defining modern workflows for in-place application modernization, optimizing code for specialty processors, and reducing MIPS at scale. I've worked extensively with CSC's Life70 and Life-Comm platforms, leading end-to-end delivery of new products and riders.
Alongside the engineering, I've spent years setting up and streamlining onshore and offshore delivery centers, facilitating agile transformation for offshore teams, and managing direct client accounts — including eight years based in the USA as a client liaison manager.
