Zac Lanzon

Software Engineer

From 2021 to 2026 I worked on the .NET loan-approval platform on AWS that every Rocket Mortgage loan needs approval from. My team and I took it from MVP to final cutover. I am currently working on the Linux side of NVIDIA GPUs: display-driver patches and hardware telemetry tools.

Current interest: running AI models on local hardware, and the Linux GPU driver stack.
