What I'm building and why

A quick introduction to who I am, what I'm building, and what I plan to write about here.

Hello

This is the first post on this blog. A good place to explain what this site is about and who it’s for.

I’m Ricardo, an Android developer based in Porto. I’ve been building Android apps professionally for a few years, Android Automotive, AOSP and recently started exploring the intersection of mobile and AI.

What I’m building

I have two Android apps in the works. This site started partly because I needed a professional home for them — but it’s also a place to write about what I learn.

What I’ll write about

Four main themes:

  • Android — architecture decisions, Jetpack Compose, Kotlin, lessons from real projects
  • AOSP — system-level Android, custom builds, things the official docs don’t cover well
  • AI & Tools — using LLMs in apps, automation, what actually works in production
  • Builder Log — the process of building and launching as a side project

Why English

Most of what I want to write about is technical and niche. Writing in English means reaching the people most likely to find it useful — regardless of where they are.

That said, I might write some posts in Portuguese too. We’ll see.
