Slides: https://gaborbernat.github.io/pycon-us-2019/#/ I work at Bloomberg, a technology company with more than 5,000 software engineers worldwide -- 2,000 of whom use Python in their daily roles. I'm part of the Python Guild at the company, a group of people dedicated to improving the adoption, usage and best practices of Python at the company. I've given five presentations to various groups within the last two years. I am the maintainer of the virtualenv package (tool allowing the creation of Python virtual environments) and the tox tool (allow for easy testing to ensure code works under multiple Python version/library versions).
