  • Infiniverse

    Infiniverse is a decentralized augmented reality platform and persistent virtual world on top of the real world. The platform allows users to place persistent content in the world, which remains in the same physical location even after the user has left the area or quit the application.

    Due to the scarcity of real-world space, users must purchase or rent “land,” the digital layer of real-world locations, in order to place persistent content there. Infiniverse has its own economy and virtual currency, Infinicoin, which is used to register land and make transactions on the marketplace.

    I led the project vision, technology architecture, partnerships, funding, and operations. While the project was ultimately put on hold due to a lack of funds, I am proud of our achievements, including being selected to pitch onstage at AWE 2018 and for collaboration and partnership with Samsung Next.

  • HoloWeb

    HoloWeb is a 3D, holographic web browser for the Meta glasses platform. It allows users to create unlimited web tabs, which live in the 3D space around them, and interact with the AR browser with their hands. HoloWeb was the first officially released Meta application, for which I was the sole developer.
