Put the direct link to your github in your resume so they dont have to search it

Lol. You are fine.

If it ever comes up (and I doubt it ever will), the answer is a simple "that's not me".

The Internet is a chaotic place. Name collisions are common. Professionals understand this.

It's fine, most places won't search your github username on a search engine. It's mostly just the places which require security clearances that do background checks that deep. So you'll be fine as long as you're not joining CP0 or smth.

Can't you just delete your Reddit account (delete all your comments/posts first), and the problem will be solved?

I have never googled anyone's name or GitHub account. But I'd also be paranoid if I were you to be honest. I don't think your career is fucked though

Since the universal response seems to be that I'd be fine (not a single person said I'd be screwed or deal with much setback) I'm trying my best not to worry about it now.

Pretty sure you can change your GitHub username. At least I did, but it's been awhile. When I got serious about my career I changed my professional online presence to use my real name.

Iirc it said something like, urls using your old username continue to work until someone comes along and makes a new account using your abandoned name.

Edit: here's GitHub's current docs on this, there's a few gotchas worth considering... https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-personal-account-settings/changing-your-github-username

Update: The person on the archive removed it!

Make a reddit account titled TheRealYourName. Split time between commenting how cute puppy photos look, how good certain attractions are in your local sub, and some actually insightful comments on some domain specific subs.

After a few months you'll have a track record you can point to.

Whats ur github username?

If it's that bad, change your name. There's nothing special about our names. They are just unique identifiers. Pick a new one and be more reserved about what you post.

Cannot you maybe simply download all the repo you made on your GitHub account and simply creates a new one, and finally, delete the older one?
