Senior Android Engineer with 15+ years in mobile.
I explore new product ideas with AI, design open protocols that let any AI agent interact with the real world, and share what I build and what I drop along the way.
- Open protocols & specs for AI agents
- MVPs of ideas I'm validating in public
- Android + AI experiments (Kotlin, Jetpack Compose, AI tooling)
Specs and code are in English. The conversation happens in Spanish on X and LinkedIn. Found a flaw in a spec? Open an issue, that's exactly what I'm looking for.
