01 — About

I translate complex problems into
elegant, fast interfaces.

I'm Juan Carlos Cruz, a Senior Frontend Developer based in Santo Domingo, Dominican Republic, working with companies across EdTech, Healthcare, Staffing, and consumer apps.

My edge? I sit at the intersection of engineering and design. I care deeply about the end user, which means the products I build aren't just clean in code — they're a pleasure to use.

◈

Web Applications

From design systems to full-stack SPAs. React, Next.js, Angular, Vue — I architect for scalability and ship for users.

◎

Mobile Apps

React Native & Expo apps that reach real users. I've taken apps from 0 to 14k+ installs with polished, performant UIs.

◇

Design Systems

Storybook-driven component libraries and design tokens that let teams move faster and stay consistent.
