I work at the intersection of systems, people, and delivery.
My career began with building websites and business applications. It grew into leading an AMI and electronic billing program, where every technical decision had to connect with real operational needs.
Today, I’m building on that experience with focused learning in EDI/B2B integration, data transformation, APIs, and enterprise systems. I’m interested in bringing that combination to an integration team, including opportunities at OpenText.
