QSMP

Overview

QSMP is a multilingual Minecraft community platform. It connects creators and fans across languages with native Android (Kotlin, Jetpack Compose) and iOS (Swift, SwiftUI) apps, a Node.js / TypeScript / MongoDB / Redis backend on Kubernetes, and a self-hosted real-time translation pipeline (faster-whisper → NLLB-200 → FastAPI). Core product surfaces include real-time chat, Communities, notifications, and authentication — scaled for ~100K monthly active users.
