About me

I’m a curious craftsman

Ronald Lopez at work

For 8 years I was the founding designer at OneLocal (YC S17), where I helped scale it from zero to a multi-product B2B SaaS platform with 2,100+ partners. My design work spanned across 7 products, 2 mobile apps, and 100+ client websites, as well as, sales decks, marketing materials, and interactive demos. Most recently, I spent 4 years at Legend, designing for Covers, one of the biggest names in sports betting.

My work sits between design and front-end code, so the fidelity of a mockup rarely stops at handoff. I want the shipped product to match the intent of the first sketch. AI workflows are now part of that process, from synthesizing research to prototyping in code, and 13 years of shipping tell me which outputs are worth keeping.

If you have a product or brand that needs care, clarity, and craft, let's build something good together.

Portfolio Design System

The portfolio you’re on now, designed system-first in Figma, then hand-coded so design and build share one source of truth.

Design the journey first, then layer thoughtful craft on top. When the foundations are right, the experience feels natural instead of forced.
