Looking for a mysql/mailwizz expert


Hi, i have a mailwizz installation with multiple clients on a very powerfull server on OVH.
This server sends a few million campaigns a day but the SSD is getting full and it is becoming impossible to work on mailwizz due to a 32core server being at 100% cpu usage during campaign sendings.
I need an experienced person on this matter to take a look into it and fix these problems, also try to clear up the mysql databases without losing opens and other important statistical data in the process.
This is a 128GB RAM server with 32 cores and 2 ssd in raid1 with about 480gb.
It is also very important to talk before any modification to avoid downtime to the users.
please contact me with price for the job thanks
