The best way to reach me is by email: qa@hotenov.com
Note that "qa" means "questions & answers". You can write anything you want to this mailbox.
I try to reply during the day (or the next day after weekend).
Your email may be filtered as spam by a mail service provider, so I can miss it. In this case, you can write me a direct message in LinkedIn or Twitter.
I also have a Telegram account. I think you can find me there. Use the search power!
