maybe not the recruiter but the hiring manager or prospective colleagues who'll interview you later?

not the number of stars, but I like looking what people have done online ie GitHub/blog. I feel like it is a nice thing to talk about.

I know it's an unpopular opinion these days cause everyone wants work life balance and not work beyond the office but it's always nice to see projects you've worked on it does show some interest. also while one can fake GitHub activity it's hard to fake well thought out and cared for projects.

it's easier to fake metrics from your previous jobs like I saved X amount of money for the company or had Y efficiency gains.
