"He has a strong visual eye and a high bar for craft, consistently bringing a level of polish and attention to detail that elevates the product. Working in the complexity of Medicaid-focused healthcare isn't easy, but Efrain navigated it with curiosity, rigor and care."

About me

I've spent 8 years in health tech at Oscar Health and then Cityblock Health, where I've designed for clinicians, care teams, and patients.

I collaborate closely with product and engineering because I know the best solution won't come from one person working alone. I'm drawn to products and services that improve people's health, wellbeing, or access to care.

Beyond work: I work on a music-related personal project with Claude code, mentor design students, and get way too invested in niche board games.

Experience

My path to product design led me through customer support and insurance operations. Along the way I was managing bugs from support calls, writing user stories with PMs, and doing field research in doctors' offices. It all made me a better designer.
