Earlier quoted context omitted.
Am I the only one who finds that type of phrasing distasteful? I'm sure he didn't build any of those alone, and as a "leader" and a product person he probably didn't do much of the "building". Seems like he was mostly in an advisory role for Drupal, Docker and MongoDB, he didn't exactly build them.
I never intended this statement to be taken as if I built these alone. Thanks for this candid feedback. Perhaps a more accurate wording is: "You may know me from helping to build the Go Language, Docker, MongoDB, and Drupal & creating Hugo, Cobra and spf13-vim"
Having worked on all these should be good enough you don't need to embellish and constantly overstate and lie about your contributions. Let other people talk about how great you are.
