About

This is where all my personal projects live. I have a keen interest in clean energy, smart homes, and building things. My day job is installing EV chargers for a large UK energy supplier. Of course, like anyone in 2026, I lean heavily on LLMs to build faster, while making sure I understand and can validate the output.
