If you're looking for privacy from your current and possibly future employers, you can obtain that by using a pseudonym online and taking basic measures to make yourself hard to dox. If you want privacy from the US government, that's not going to work.

Also, getting doxxed isn't entirely bad because it can open doors as well as closing them. Depends on how you leverage it. You just don't want the US government and/or the government where you live as your adversary.
