Mobile lead (Brazil): hands-on ownership of iOS and Android in Swift and Kotlin; C++ when native performance matters; and the APIs and integrations those products depend on.
Ubook — Co-founder; I lead mobile, architecture, and performance. We built a large Brazilian company in audiobooks and spoken audio, raised growth capital, and expanded internationally. Exame on the funding round (2019).
Open source — Libraries and runtimes I maintain for the long term across native stacks, web tooling, and AI-related systems, with the same engineering discipline I bring to production codebases.
Godot — Engine-side work and native extensions where my mobile store experience informs how exports behave on iOS and Android.
Apps & games — Products I publish under my own name: applications and games with full ownership through distribution, separate from employer roadmap work.
