About Me

I'm an engineer with a passion for understanding how things work

At the moment, I'm a Principal Engineer at L3Harris, where I help build high-performance RF and signal processing systems, and with Oxford's Space Instrumentation group where we build science payloads for remote-sensing satellites. I'm a firm believer in open source, an avid reader, an occasional baker, agus bidh mi ag ionnsachadh a' Ghàidhlig

I graduated in 2020 with a first-class bachelor's degree in electronic & electrical engineering, and in 2023 I achieved incorporated engineer accreditation through the IET
