# Daniel Morales González > Lead Mobile Developer at Joe & The Juice. Copenhagen, Denmark. I lead mobile at Joe & The Juice, where the React Native app serves more than two million guests. Before that I shipped medical-grade diabetes software and AR on Android. On the side, I run nyborger, a citizenship-exam app. Barcelona-born, Copenhagen-based. I started in aerospace engineering, left after a year for software, and have been building mobile products in Denmark since 2018. I care about the parts users never see: architecture that survives a growing team, releases that roll back cleanly, and SDK integrations that do not wake anyone up at night. The parts they do see should feel inevitable. ## Experience ### Lead Mobile Developer · Joe & The Juice 2026-03 – present · Full-time · unit of work: Direction - Lead mobile development for the Joe loyalty app, serving 2M+ guests across markets. - Set technical direction for the React Native codebase and mobile architecture. - Drive cross-team initiatives with product, backend, data, and growth. - Own the integrations the business runs on: payments, analytics, and engagement. - Mentor developers and raise the bar on reliability, releases, and standards.
