Hi, I'm Jorge 👋
I build web & mobile apps for health, fitness, and local businesses — and turn their data into decisions.

About

With 5+ years building web and mobile applications, I've helped fitness studios, startups, and local businesses go from idea to shipped product. I specialize in React, Next.js, and React Native, and I'm combining that with health data analysis — Apple HealthKit, Supabase, and Python — to help companies like Bita Fitness and Staminapp make sense of their users' data. I work directly with founders and business owners, focused on delivering real outcomes: more revenue managed, faster workflows, and products their customers actually use.

What I Build

Web & Mobile Apps

Custom platforms for health, fitness, and local businesses — React, Next.js, React Native.

Health Data Analysis

Apple Health, wearables, and user activity turned into dashboards and personalized insights.

SaaS & MVP Development

From idea to launch. I help founders and business owners ship their first product fast.
