Looking for people with experience in performance optimization

Hello bubblers! We are preparing to reach a new level of users in our App and we are looking for some people who know how to load test the app. We can get 10+ to 100k users accessing our App concurrently, and I just don’t know how we would stress test that level of capability. Mainly looking for people who have been through this to talk about strategies, and we’ll be happy to oblige if it’s more than a quick chat or whatever. Thanks in advance - looking forward to connecting!
