Time is precious and I make a point of respecting both yours and mine. The best way to reach me is asynchronous means of communication which respect my time and focus. Hence you can send me e-mails or a SMS, to which I’ll respond as promptly as possible.
I don’t keep track of social media profiles (I deserted Twitter after its purchase, I don’t check LinkedIn often enough), especially direct messages. Avoid these channels if you want to be sure to reach me!
