To skip creds, skip gov and bigco, esp when new :) Startups & smaller co's are the places that take on the uncredentialed CV risks that everything-aleady-works co's have too much to lose on.
Gov and bigco care about creds, esp early. Managers there are rarely judged on ultimate results as they are often far removed and just need to improve something predictable by say 1% and hit some fungible and redefinable goals. They are heavily into checklists for covering their ass in not going in the other direction: "Your team took down prod / project was late: why did you hire unaccredited ppl? You run a B team. My team needs 2x budget bc we have all CISSPs and PhDs, and are not responsible for final delivery bc that's grunt work." They do matter a bit later too, but more fungible: someone close to me is actively going through a ~50% pay negotiation based on the same work but differently creds & math being recognized.
Startups and smaller companies dont need to protect their fiefdom but make it exist & grow, so credentials mostly matter less and projects matter more. Early on whether you can actually code, which projects show. Later, whether you can actually run a project through various stages, vs ride on the coattails of someone else, which takes 1-3 years.
