About Me
I'm a software developer based in Madrid, Spain. I build apps for Apple platforms, developer tools and web products. I use AI agents in my workflow and apply software engineering best practices to build reliable, maintainable software.
Experience
Over 15 years building for Apple platforms with Swift and Objective-C. My experience includes Firebase, REST APIs, MVVM and VIPER.
From Idea to Product
I take ideas from early prototypes to useful products, including native Apple apps and self-hosted web projects.
Products
I've published apps on the App Store and created open-source projects, Xcode extensions and Stream Deck plugins.
