I will do my best to get back to you as fast as I can.
If you have a relatively deep or complex question, please give me some time to properly respond.

I respond to every single email (unless it’s spam). If you didn’t get a response within, let’s say 48 hours, feel free to remind me (perhaps I missed it somehow). I ask you for forgiveness in advance.
