OONI Probe runs in over 200 countries. Journalists and activists use it to detect internet censorship — and for the past 4+ years, I've been the one shipping it on Android and iOS. Before OONI, I spent 3+ years at Zinger Systems building cross-platform apps: a vehicle tracker processing live GPS from IoT devices, a civil status registration system for local government, and a water utility monitoring platform. Kotlin Multiplatform and Go for the code. Docker and Kubernetes for the infrastructure. I care about software that gives people access to information they're told they can't have.
