BIO
Quinn is an engineer/manager who picked a *fantastic* time to co-found a company making deep learning pipelines that improve themselves. Before that he was at Ouster (leading data engineering / data viz), Cruise Automation (leading ML data engineering + labeling), and Graphistry (1st engineering hire, so a bit of everything). Working on self-driving cars has given him an irrational hatred for trees and shrubbery.
Ex-company, school and discipline below are derived from this bio. Nothing is inferred when the bio is missing.
