If you want to reach me, try email, XMPP, or reticulum. If you email me, consider encrypting your message, despite its trivial nature, and if you engage in XMPP, I can do OMEMO, but it requires that we both add each other as contacts first, at least for the client I use.
You can fetch my public key with T383838gpg --locate-keys, if you're a ProtonMail user it should fetch them automatically. If all else fails, you can download the key from here.
