There are lots of ways to be in touch!
Most of my code is on github, including the code for this site! Some other code is on gitlab, though I mostly put private repos there.
I spend a lot of time on julia social channels, including slack (@kescobo), zulip (@kevin Bonham), and discourse.
I haven't been doing much tweeting since the Muskpocolypse, but when I did, it was @kevbonham. More recently, I've been on Mastodon at @email@example.com.
I've got a LinkedIn and Polywork, though don't count on timely replies there.
