About Me

Leadership and product

As co-founder of Ubook, I led mobile, architecture, and performance across a major audiobook and spoken-audio platform in Brazil, from early product through growth, international expansion, and fundraising. That work was hands-on ownership of engineering strategy and delivery, not only roadmap oversight.

Technical scope

Day to day I work across native mobile on iOS and Android in Swift and Kotlin, with C++ where performance, shared cores, or platform integration require it, and Python for backend and tooling. I care about the full path from APIs and infrastructure to store-ready clients and long-term maintainability.

I maintain open source with the same standards as production codebases. I also invest in AI-adjacent systems and agents where they need to run reliably on real devices and servers. For games, I use Godot and native extensions when store and platform behavior matter.

Mobile and native OSS

A fuller map of mobile-related repositories lives on the Mobile page. Two projects that often anchor cross-platform work:

• xplpc — lightweight cross-platform procedure calls across native stacks.
• nativium — modular C++ toolkit template for native libraries and SDKs.

AI and automation

I created IonClaw, a cross-platform AI agent orchestrator for mobile, desktop, and server, focused on real-time automation and on-device intelligence where that is the right tradeoff.

Godot

I ship games with Godot and maintain open source plugins for native iOS and Android integrations (Firebase, RevenueCat, safe area, ATT, and related concerns). The full list is on the Godot page, with sources under godot-x on GitHub.

Teaching

Instructor for Mobile app development with C++ (Android and iOS) on Udemy.

How I work

I optimize for software that stays understandable as it grows: clear boundaries, measurable performance, and changes that teams can repeat without heroics. I prefer long-term collaboration and steady improvement over one-off spikes of activity.
