// about
The human in the loop
more about →

By day, I build AI for game development at NVIDIA. By night, I'm an avid gamer, amateur photographer, and proud dog dad.

My career has followed the collision of graphics and ML — from game engines at Crystal Dynamics and DreamWorks to large-scale platforms at Microsoft, then to the frontier at Unity, neural rendering for self-driving at Zoox, and now NVIDIA.

I write about what I learn — performance, ML, mental health, the human side of being an engineer who measures everything. The learning happens in public.
