Senior Software Engineer at Checkit
Enables public access and secure configurations through reverse proxy
The primary valuable feature of NGINX for me is its ability to provide a reverse proxy. I have found that this feature supports our local server, and I am able to connect through our DNS system, making it accessible publicly. Additionally, the integration with SSL certificates and the configuration capabilities make it a valuable solution for my use case.
