I'm a cybersecurity leader passionate about building pragmatic security culture and practices: The social buy-in and the technical.

The blog has security, maths, physics, music, and some life. If you're interested in working with me, note this blog is informal.

I came from mathematical physics and pure mathematics. My interest lay in areas that were either stagnating or ivory tower. I'll temporarily spare you the rants about the axiom of choice and the prevalence of certain unfalsifiable theories.

I wanted to do something useful, complex, and as passion-sparking as physics is to me. While mulling that over, the reflection of my battle-tested tinfoil hat guided me to information security.

I learnt programming, system administration, web development (1.0), forced my friends to use OTR and PGP, and hacked through OSCP, OSCE, and OSWP. Since those early days, I've acted as CISO/Head of Security at several start ups. I emigrated from Ireland to glorious Switzerland in 2019.

Other than that, I love cooking, self-hosting, documentaries, guitar, science, and wit.
