Web, mobile & design systems

01 — About

Complex systems.
Clear outcomes.

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

I build end-to-end web and mobile solutions with React, React Native, TypeScript, Node.js, and PostgreSQL, from accessible interfaces to REST APIs, business logic, and relational data models.

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.

01

Web Applications

End-to-end web products, from polished interfaces to REST APIs and relational data. React, Next.js, Node.js, and PostgreSQL.

02

Mobile Apps

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

03

Design Systems

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