Real-time hologram video calls for Holoconnects, shown at CES

Holoconnects makes Holoboxes, life-size hologram displays used in shops, hotels and events. A person in a studio appears as a live hologram inside a Holobox anywhere in the world and talks to people in real time. I led the frontend for the platform that runs it all: the customer dashboard, the live studio app and the system that shows ads on the displays. The product was shown at CES 2024 and CES 2025.

A hologram call only feels real if there is almost no delay. The kiosks needed a reliable peer-to-peer video connection with less than 500ms of latency, while hundreds of displays in different countries also played HD promo content on a schedule. Customers also needed one simple place to see every Holobox, its status and its call queue.
