About
I have spent the last decade building games and interactive media: AAA mobile, VR interactive films that premiered at Venice, location-based VR arenas, training simulators, advergames and retro homebrew.
Since 2020 I lead the Unity engineering team at Kodansha VR Lab, owning the core systems and tools behind every title and bridging production and engineering so films actually ship. Before that I was a graphics and tools engineer on Unity and Unreal projects at Play Next Lab, and co-founded Radian Development Studios in Mexico City.
Off the clock I ride bicycles, chase craft beer, and ship small web games under the name ConfusedGameDev.
