I build and modernize scalable Android products with Kotlin and Jetpack Compose.
BrazilWhat I'm looking for
I've built and modernized Android products at Vetrec.io and Jobsity/Glance, from migrating a 5,000+ user React Native app to native Android to supporting a 30,000+ user product and rebuilding its UI SDK.
I lead architecture, complex integrations, and delivery across mobile, web, cloud, IoT, and voice-recognition products. At VIRTUS, I led teams of up to nine engineers on products serving up to a million users, translating client requirements into technical plans and shipping in iterative release cycles.
I work hands-on with Kotlin, Jetpack Compose, Java, MVVM, Retrofit, OkHttp, Room, React Native, and AI-assisted development workflows to build maintainable, performant software.
