About

Hi, I'm Jesse.

JESSolve is run by Jesse (King Chung Cheung), a structural engineer based in London. I set it up to give homeowners, installers and builders straightforward structural advice: the right answer, explained clearly, without the runaround.

Alongside consultancy work I build digital engineering tools that make everyday calculations quicker and more transparent.
