Worked my way up from a field support IT technician to an ITSM management consultant, trainer and instructional designer. Still hands-on with Linux (mostly), Windows, virtualisation, networking and data centre ops etc.
I'm also a STEM Ambassador; helping school students tinker with Raspberry Pi, Arduino, BBC micro:bit, electronics etc.
