About me

I’m Chema Martínez, a Senior Product Designer with a background in visual design and a long-standing curiosity about how things work on the web.
I spent 11 years as the sole designer at a company, helping turn a platform for creative opportunities into a more capable, accessible product for both creatives and the organisations supporting them.
I enjoy making complicated journeys feel clear, useful and genuinely enjoyable to use.
