## What This Site Is

antwi.dev is the personal portfolio of Jermaine Antwi, a London-based design engineer, product builder and HCI researcher. It isn't a product or a service: there is nothing to sign up for, buy or download. It shows his projects, writing and research, and how to reach him. It's for people with product, design engineering, HCI research, education technology or fintech work to discuss with him, for anyone asking him to speak, and for readers of his writing and research.

antwi.dev is the current site and the source of truth. maine.is-a.dev is an older portfolio that is out of date: where it disagrees with antwi.dev, antwi.dev is right. www.antwi.dev, antwi.is-a.dev, codemaine.vercel.app and maine-dev.vercel.app are other addresses for this same site.
