While booking, you will be asked to describe what you want to discuss. I will confirm the meeting by mail if it is a subject I can help you with. The discussion can be on Skype, Google Hangout, or your favorite video conferencing system (while booking, you will be asked for it).
This is an experiment ! I opened consulting hours between March 31st and April 11th. If this goes well, I will add more; if it does not go well, I will cancel everything. Also, I will do my best to answer your questions and help you with your MySQL challenges, but I cannot replace a full-time DBA on your team. Also, I will not be able to get a complete picture of your situation in such a short time, so you will have to be smart in deciding if you want to follow my advice or not.
Good luck to you all and courage during these strange times !
