I architect and secure network infrastructure to build a faster, more resilient internet. I currently run technical strategy for service providers as a Principal Solutions Architect at Cloudflare out of Lisbon, after spending six years engineering solutions in London.

I am fascinated by the dual nature of technology, its immense power to elevate people's lives, and its equal capacity to disrupt them. I am obsessed with the first path. I get my energy from fixing broken systems and solving hard problems, whether that means deploying zero-trust architectures at scale or writing small tools in Go for my homelab. The satisfaction comes from the same place: solving a real problem.

How do we build networks that actually serve us?

Here is where I document the things I build and the systems I break.
