Leonard Cheung — Design & Engineering Portfolio

it's 2026

> Currently: Building products and exploring the intersection of design & engineering

I design and build things. From browser extensions to drones, I'm driven by the idea that good design alone can evoke emotion and solve real problems.

Realising I could not only understand but also create things myself was a turning point. Now I spend my time iterating on ideas, connecting with people, and (formerly) crypto mining.

I think by building. When I'm not coding or doing a project, you'll find me swimming, playing chess, exploring philosophy (I think?), reading, or planning the next thing.
