First of all, thank you for wanting to get in touch! I might not be the easiest person to get a hold of, as I don't really use typical social media any more, but hopefully one of the methods below will suffice.
I do not respond to unsolicited job offers or recruiters. Please respect this, thank you.
The easiest way, and I usually respond pretty quick.
I generally accept connections from people I have met, worked with or otherwise had enough communication with that I feel comfortable to call them a professional contact.
Public key enabled, and proof of identity. This is a good way to getting in contact with me as well, specially if you want to send an encrypted message and you do not have me on Signal.
