I've always admired Project Jupyter from afar and to join as a JupyterHub maintainer is definitely a LIFE GOALS achievement for me. The difference between then and now is that I better understand the power and impact of the open source community and *people*
We’re incredibly proud to announce that Jenny Wong was invited to join the JupyterHub team as a contributor and maintainer!

But small win, recently made my first PR to JupyterHub fancy-profiles to add support for ARM architecture.
& now I have JupyterHub running on an NVIDIA DGX Spark (via k3s).
Also have CUDA/RAPIDS based image in rocker for python+R envs, rocker/cuda:arm64
