What I'm looking for

I’d like to specialize in frontend development, expand my experience with Flutter and React Native, and learn relevant languages like Kotlin and Swift.

At ADCOMUNIDAD, I take charge of development and design for a cross-platform mobile app built with Flutter. I set its technical and visual direction, from initial architecture through launch.

I previously developed cross-platform Android and iOS apps with Flutter and Kotlin at Kappowsky. I also developed and released Subasta Forestal, which reached over 500 downloads, and handled updates to SBC Gasolineras and Museo das Peregrinacións.

At Servicios Reunidos, I developed a Flutter app for my bachelor’s thesis that extracted information from pictures using a neural network, alongside a website in Vue.js. I’m interested in specializing in frontend development and expanding my experience with Flutter and React Native while learning Kotlin and Swift.
