Hi, I'm Arturo 👋

I'm an Android developer from Mexico passionate about building free and open-source software.

My main project is OpenTune, a YouTube Music client for Android built with Kotlin, Jetpack Compose, and Material Design 3. Besides the app itself, I also develop and maintain the infrastructure behind it, including APIs, backend services, and web tools.

• 🎨 User interfaces built with Jetpack Compose and Material Design 3
• ☁️ Backend services using Cloudflare Workers and R2
• 🌐 APIs and web tools for the OpenTune ecosystem
