Summary
🤩
Rockstar🎓
Top SchoolMaciek Chociej is a software engineer in New York with 10 years of experience building high-performance systems at the intersection of game engines, physics simulation, compilers, and large-scale ML infrastructure. He has shipped production features that drove meaningful business impact—a suggestion engine for a $1B/year ads product that improved conversion by ~7–12%—while also working on cutting-edge research applications like teaching a multi-eyed, 20+ DOF robotic hand to manipulate a Rubik’s cube. His technical breadth spans rendering and computer vision stacks for large-scale RL, procedural 3D environment generation for navigation agents, and a domain-specific language plus codegen framework for dense numerical methods. Trained in theoretical computer science with graduate work in grid computing, he combines rigorous academic grounding with hands-on engineering to optimize computational pipelines and simulators. Colleagues describe him as someone who comfortably moves between low-level performance engineering and system-level design, often finding non-obvious algorithmic or tooling shortcuts that unlock scale.
