Note
Open to opportunities: hybrid or remote work in the Centurion / Pretoria area.
Several of these are government systems, so I don't link them directly. Full write-ups are on my portfolio.

I keep my study notes in public at knowledgebase.devbridge.co.za: a regularly updated hub covering cloud, databases, Linux, networking, orchestration and programming. They're rough working notes, tidied with an LLM, written as I learn.
