I know that mentioning downvotes usually invites more downvotes, but...

I'm surprised you're being so heavily downvoted for your question. Engineering teams (and software companies) come in all shapes and sizes. It is absolutely reasonable for even an experienced engineer to have only worked at companies with a handful of repos.

Rather than downvoting, it would have been helpful to explain why your company has opted for such granularity (perhaps engineers or teams have a high level of autonomy, or your software is highly componentised and built from a great many, separately managed, parts).
