Be careful - it's one thing to be proud of tangible achievements, like building something, or solving a hard problem. Titles, becoming a "manager" or "lead" is often just false currency - something you're given as alternative compensation i.e., they pay your ego, instread of your bank account. If you don't actually prefer the actual act of leading or managing, and if it doesn't come with a significant pay increase I would be careful of valuing it as real progression.
I have been in yearly review meetings where we've discussed engineers, who wanted "career progression", so we would promote them to a different level or make them a "manager" with mostly hands on duties, since it was free to do so (they didn't get paid for it - titles are free). Last year, I turned down a "Managing Director" job, to keep my "coding job" since at the end of the day, it really is only about how much you enjoy your job and how much you get paid - everything else is just fluff.
Thank you, this is a very good point and something that I have considered in the past. I guess, all I am really after is a sense that my career has progressed. And I am not sure how to measure that.
