About me
Intro
I've spent nearly two decades keeping enterprise systems running when it matters most — high-stakes financial and insurance platforms where downtime is never an option. At Optum, I led a production support team that sustained 99% system availability for four consecutive years and cut incident turnaround times by ~80%. At Manulife, I served as a Subject Matter Expert bridging critical mainframe knowledge and modernization efforts across Canada's technology division. My edge is the combination of deep technical fluency (COBOL, DB2, z/OS, CICS) and the ability to lead teams, navigate regulatory mandates, and communicate clearly across organizational layers. Currently completing a Postgraduate Certificate in Global Business Management at Howest University (Belgium), I'm expanding toward roles at the intersection of enterprise systems, business continuity, and digital transformation. Based in Brugge, Belgium | Open to opportunities in Europe and globally.
