Internal Security Lead at an MSP based in Yorkshire. Focused on identity-first security, Microsoft 365 / Azure, and reducing trust boundaries in real environments. Most of my time is split between security architecture, investigation, and figuring out where systems don’t behave how they should.

This is a personal knowledge base covering InfoSec, systems engineering, and infrastructure.\
It serves as a working journal - documenting lab builds, write-ups, network experiments,\
and things that don’t quite sit right.

* Identity-first security and Conditional Access design
* Network trust boundaries and segmentation (home lab + real environments)
* Observability and detection (SIEM, logging, "what actually happened")
* Early exploration of OT and signal integrity concepts
* Automation and tooling (Go, scripting, infrastructure)
