CISSP (ISC2)15+ yearsLondon

The Short Version

I founded Blue Icon because too many small businesses get terrible IT support — or none at all.

Before this, I spent 7 years as IT & Security Manager at Memrise, where I built the IT department from scratch. Before that, I managed infrastructure for a 4,300-person school across four sites.

I'm hands-on, direct, and I don't hide behind jargon. When you work with Blue Icon, you work with me.
