I have been an Android engineer for more than 8 years, and I have been working with Kotlin since 2015. In addition to my extensive experience in Android, I have also been actively involved in iOS development for the past 3 years. Notably, I have dedicated 4 years to working with Flutter, showcasing my expertise in cross-platform mobile app development. I currently work as a Mobile Team Lead at Worldline Iberia. I am also fascinated by the world of Generative AI, and I have dedicated 1 year to exploring and working with this innovative technology. As a dedicated software enthusiast, I have been a remote worker since 2017, and I strongly believe in the principles of open source development.
