Recent focus has been on CIAM identity backbone implementations for state governments as they go online with services due to the COVID-19 pandemic.

Previous experience

Worked mainly on migration of state identity services from on-prem mainframe identity and access management to cloud-based citizen single sign-ons for access to government agencies and services. These websites handle hundreds of billions of dollars for millions of citizens. And with the pandemic, they have become targets of massive identity fraud. While at Deloitte, also contributed to internal strategic identity projects and was a co-developer and facilitator of Deloitte University's Identity Boot Camps. Just prior to the pandemic, acted as interim Identity manager for a client hospital in Philadelphia as it upgraded it hospital systems to more modern digital services.
