About

👋 I'm Gonzalo Fuentes, an iOS developer and software engineer based in Madrid.
My passion lies in creating innovative mobile solutions that make a difference in people's lives.

🚇 Since 2017, I've been developing Metrociego Madrid, an iOS app helping visually impaired users navigate Madrid's metro system autonomously. This project has grown to over 8000 downloads with 800 monthly users. I've honed my skills in SwiftUI, CoreData, and real-time location tracking, always striving to improve app performance and user experience.

🛰️ Professionally, I work at GMV on data processing for Meteosat Third Generation satellites, with ESA and EUMETSAT. This role has expanded my expertise in Python development.

💻 With a background in Computer Engineering from Universidad Autónoma de Madrid, I continuously enhance my iOS development skills, exploring new Apple frameworks and design patterns. I'm always eager to take on new challenges that push me to grow as a developer.

🌍 When I'm not coding, I am traveling and exploring new countries and cultures. It's a great way to unwind and gain fresh perspectives that often inspire my work in unexpected ways.
