Ask HN: What did you do that helped you reach senior title?

I doubt there's a single, pivotal thing that you can do to reach the top of the IC ladder, but, besides looking into your internal company career ladders, what have you done, maybe by going the extra mile, or taking ideas from HN or nice subreddits that really helped you in any way?

I've managed to get promoted to a mid level position by actually streamlining our onboarding process together with my manager during a time of team growth at the job, for example.

Do you have similar stories to share maybe?
