Memento AR — Location-Based Augmented Reality Social Platform
Memento AR is an innovative AR-driven social platform that blends storytelling, exploration, and creativity into real-world environments. Users can create and discover AR trails, digital galleries, immersive adventures, and interactive experiences anchored to physical locations. While the cross-platform AR applications were built in Unity by a dedicated team, I owned the complete backend microservices ecosystem that powers content creation, discovery, social interaction, and scalability.
