Hi, I'm
Yulimar Duque
I build mobile apps from zero to production. React Native Developer with 4+ years shipping products to App Store and Google Play.
The person behind the code
I'm a React Native developer with 4+ years building mobile apps. I've led the full development cycle — from architecture decisions and feature development, to setting up EAS Build, managing App Store Connect and Google Play Console, and shipping real products to production.
I'm passionate about sharing what I learn. Beyond building, I create technical content and practical guides so other developers can shorten their learning curve — especially around the app store publishing process, which is often more complex than it seems.
