Contact
No need to book a call: an e-mail and two sentences about what you want to change or what is not working are enough. I reply within one business day, in the same time zone as Berlin (CET/CEST). When I am on holiday, an automatic reply says so.
Thank you, your message arrived.
I will reply from jacob@codelevel.pl with a few short questions or straight away with a concrete proposal. An automatic confirmation with the reply date is on its way to the address you gave.
Prefer plain e-mail?
jacob@codelevel.plUrgent issue?
Write with URGENT in the subject. I read those first on business days.
