This is the easiest place to get in touch with me and I respond as soon as I can.
If you prefer to use ProtonMail then you can also email me here.
My background is decently well covered here. I accept connections from people I've met, worked with, spoken with or otherwise had enough interaction to feel that I can call them a professional contact. I don't usually respond to requests from people I don't know.
I've cut down on using Twitter recently but I still log in from time to time.
