About Julian

Bridging the gap between security and the people who build software

I spent the first decade of my career in the technical trenches โ€” building web application firewalls, running penetration tests, and designing security architectures for enterprises across Europe, the Middle East, and North America.

The last decade has been about helping organisations get security right at scale โ€” leading solutions architecture teams at Veracode, scaling the APAC organisation from zero to 27 engineers, and working with development managers and CISOs who are trying to build AppSec programs that survive contact with real engineering teams.
