If you want to contact, use email mrhelstein at mrhelstein.com – also, if you want to check Business ID etc, email. I am so darn tired of information theft that I will not post anything more detailed on this site. For those semi-curious, I do live in Finland, have full-fledged company and I also pay my taxes to Finland as well.
Email works, use it. Also, if you are more into messaging apps, I have account on both Signal and Telegram, that’s the other way.
