Required Magento,System Administration,Nginx,Redis freelancer for Magento Optimization job

Hello,

We need an optimization and a tune-up of several servers currently containing a web in Magento 2.1.9. Despite the fact that the servers have greatly high resources, they are especially slow in areas outside the cache, such as the customer area, the checkout, etc.
The project has 3 servers:
1. Server making Back and Front. It has 32 cores and SSD disks.
2. MySQL Server. It has 8 cores and SSD disks.
3. Test Server. It has 2 cores and it has everything installed (mysql and web)

The server has NGINX installed, Apache and REDIS.

It is prioritised the fact of speaking Spanish when hiring the freelance, but this is not an essential requirement.

Thank you,
