I like knowing
how things work.
I’m a qualified electrician with F-Gas certification, working across residential building services: heat pumps, air conditioning, plumbing and heating systems.
That curiosity carries into software. I enjoy turning complicated ideas into clear, useful tools—whether the result lives in a plant room or a browser tab.
