Principal Engineer, Member Of Cto StaffSifive Mar 2022 - PresentSanta Clara, California, UsMy career has come full circle, I'm back to vectors and matrices but this time it's in things you carry vs. racks in a data center. I guess in the end it's all vectors and matrices in this simulation we call life.
