When I’m not studying, I develop side projects that scratch the itch to build beautiful, performant things that solve problems.

Led development of front/back-end + designed UX. Visualises postcode-level climate data using a multi-layer map and information cards. Provides calculators which weigh multiple parameters to find savings if solar panels / an EV are used over their less eco-friendly counterparts.
