server 2019 support

My organization requires specialized support in Server 2019. Specifically, I am looking for a freelancer to provide remote troubleshooting and maintenance. We are running the application on a physical server environment, so having experience within that type of set up is a plus. This should include ability to diagnose issues, carry out system and software repairs, and provide advice and guidance when necessary. We may also need help with performance optimization and security enhancement in the near future, so if you are familiar with these areas, that would be beneficial. We are looking for a freelancer who can handle our needs efficiently and cost-effectively.
