Passion for connecting multidisciplinary teams

I’m Demetrius (Demi), an XR and 3D project lead specializing in immersive experiences, interactive design, and real-time development. Based in Portugal, I create solutions that merge technology, design, and storytelling — with projects delivered in VR, gamification, training, and digital reconstructions.
But my true strength lies in connecting people. I believe great ideas are born from collaboration. My role goes far beyond the technical: I build bridges between artists, designers, and developers, fostering a positive, easygoing, and creative environment where everyone feels valued. To me, leadership means empowering, inspiring, and creating space for every talent to shine.
Most of the time, I’m a hands-on tech lead and art lead — often both at once. I talk code with devs and sit down with artists, modelers, and designers as one of them. I design interfaces, model 3D, build assets, and care about how things look, feel, and work. Because I’ve done the work myself, I get the challenges. I know what it takes. And my focus is always on making sure things actually get done — and done on time.
