In this UNESCO project, I collaborated with the team at DeuSens Hiperexperiencia on an interactive web application that lets users explore cultural heritage through scroll-guided navigation in a 3D environment. My contribution focused on implementing functional components on the frontend, integrating a multilingual support system, creating custom overlays with Google Earth and incorporating them into the web, plus performance optimisation and debugging. All of it in close collaboration with the team’s UX/UI designers, developers and 3D modellers.
