At GSK, I define global strategy and transformation roadmaps for enterprise LAN, Wi-Fi, access authentication, and IT/OT connectivity. I lead architecture, engineering, and operational governance across corporate, campus, and manufacturing environments.

At British American Tobacco, I led global technology operations across Europe and Africa, supporting infrastructure in 100+ markets. I led a major Azure data centre migration and cloud landing-zone program with an approximately £30M budget, and delivered access authentication standardization supporting 50,000+ users.

At Liberty Global BV, I directed a Software-Defined Data Centre transformation based on VMware Validated Design and delivered the first UK SDDC node. At Kreditech Holding S.S.L. GmbH, I established the SRE function for 15 engineers across two countries and directed the migration of colocated infrastructure to AWS.

Earlier, I advised C-level executives at Huawei Technologies on enterprise technology strategy, architecture, and infrastructure modernization. My work spans cloud and infrastructure transformation, enterprise networking, cybersecurity, IT/OT integration, and technology investment governance.
