Nayara Marques //  Sr product designer

I design complex products, from the first question to the shipped screen.

9 years in B2B and B2C products. I brought AI into an institutional investment platform and explored building products end to end, from market research to launch. Both run on a design system AI can build from.

A design system AI can build from

Three phone screens of the card insurance flow: pick an assistance, confirm, done

After a layoff I put my time into two products of my own. I took each one from market research to shipped code, on a design system AI can build from, and used them to learn new tools and test ways to automate a business.

About

I work where the product is hard to explain: money, freight, regulation, AI. I start with the people who use it, and design until the team can build it without guessing.

Open to senior, lead or founding design roles. Remote, from Barcelona.
