Leading IT service operations, ITIL processes, cybersecurity, cloud transformation and strategic planning.

Bridging technology
and people

I'm a highly motivated IT Manager with a decade of experience across cultural institutions, professional services and consulting in London. My work sits at the intersection of IT governance, cloud infrastructure, security and service excellence.

From managing helpdesks and security operations at the Museum of London to leading IT service delivery at the National Portrait Gallery, I've built teams, driven automation and ensured compliance across complex environments.

My academic background in Telecommunications and Computer Science (ISCTE, Lisbon) gives me a technical edge — I also have a published IEEE paper on UAV communications. I hold certifications including Prince2 Practitioner and ITIL, and I'm passionate about leveraging cloud solutions and AI to drive continuous improvement.
