About Me
I'm a Senior Software Engineer at Unity Technologies, based in Montreal, Canada, after relocating from my native Colombia. Over the course of my career, I've worked across a wide range of real-time 3D applications, from brand activation games and virtual simulators to multi-platform educational software and, today, solving complex technical challenges for some of Unity's largest customers worldwide.
I speak Spanish and English and am currently learning French. Outside of work, I'm a proud father who enjoys video games, movies, technology, the outdoors, and motorcycling. I plan to continue finding joy in life with my beautiful partner and family.
