Project Description:
Our project, GroundOS, is not just another screen manager. It is a next-generation Universal Display System (UDS) built to power the future of global mobility. We are building an "Operating System for Reality" that orchestrates massive, data-driven signage networks across critical infrastructure, from major international airports to sprawling public transport systems. GroundOS moves beyond static displays; it uses a state-of-the-art digital twin to process and react to real-time operational data. To guarantee continuous operation, the platform features a resilient, offline-first edge architecture that ensures screens keep running smoothly even if the network fails. Join us to blend high-performance Rust edge computing with modern TypeScript cloud services and help us set a new global standard for how hundreds of millions of passengers experience their journey.
