Work
Every project here shipped — to the App Store, Google Play or production web. Each case tells what the product was, what I owned and which decisions carry my fingerprints.
Own products
Built after hours, owned end to end — design, code, infra and the store listing. Every decision here is mine.

Don't Idle
A native macOS app that keeps your Mac — and your status — awake.
A menu-bar utility that nudges the pointer when you step away, so your Mac stays awake and your chat status stays active — on a schedule, and easy on the battery. Built in SwiftUI and shipped as a notarized Developer ID app with a self-update flow and three languages.

A whole church in one app — the flagship of igreja.studio, my white-label for churches.
IEQ MVA is the first church running on igreja.studio, the white-label platform I built for churches. No decision here belonged to anyone else: requirements with the church, every screen in Figma, Expo app, NestJS API, Azure infrastructure and both stores.
