I can also be found on LinkedIn.
For sensitive correspondence, use signal. Actually, do use it regardless of importance or sensitivity. My fingerprint (as of 6 Feb 2026) is

This is basically my half of the so-called “safety number”. (See Github issue #1396 for technical details.) Please note that I have depreciated the use of my GPG key 0x054bd0b41b1b6fac.
