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 built what I designed across 7 SaaS products, 2 mobile apps, and 100+ client websites. 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.

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