For a resume in data science do i need a github link in my resume? I dont rly use github but i could just throw a bunch of s*** on there

not everyone look at it but it doesn't hurt to have a few projects on it

As a (senior) software engineer the only thing on my GitHub are projects for some college classes years ago and a fork for a hack Youtube ipa lol.
I have it on my resume but I doubt recruiters even click on it.

It might be useful if you're on the graduate/junior level and you want to showcase personal projects, but as you gain professional experience it doesn't matter so much.

throw in kaggle somehow as well
