Senior Full-Stack Developer with Backend Focus

About the Project

Transforming the leisure and tourism photography experience: Powered by patented technology, our platform combines advanced association methods with an AI learning engine to enable real-time media streaming at scale, without compromising guest privacy.

The platform uses AI to recognize individuals within crowded and dynamic environments such as amusement parks and events, allowing guests to simply upload a selfie to match it with media captured in real time.
