Server configuration, Ngnix troubleshooting

The assignment is to configure the server and diagnose and fix potential overload errors such as 502 or 504. We are looking forward to a potentially longer cooperation in the future to maintain the infrastructure, perform ongoing load tests.

I am looking for an experienced person who has an idea of how the infrastructure works, supporting our IT team from the server side.

If you feel comfortable working in the environment described below - please contact me.

1 The platform stands on Laravel, we use MySQL database and cache a lot of things to Redis. Everything is hosted on nginx. Previously we had apache with no problems, but due to optimization to handle potentially high traffic, we switched to nginx.

2 We use multi-tenancy in Laravel and each tenant has its own database. In total, we have about 300 of them.
