Nicolai Brøndum Knudsen, UI/UX and Product Designer from Copenhagen, with screenshots of AmberText, Keystone Cutoffs and Keystone Meta

I'm a UI/UX and product designer from Copenhagen, with over ten years of experience building digital products. My work is mostly about making complex things feel simple, and lately I have started building some of my own ideas as well, all the way from the first sketch in Figma to a product people can actually download and use. This is where those projects live.
