setup NATS on Digital Ocean

I'm looking for a Freelancer to help me setup NATS server on Digital Ocean. This server will be used as message system for communications between computers worldwide. Local computer are mostly using macOS, and code are mostly in Python. Configurations are needed for both local computers (to listen to the remove NATS server) and NATS server on DO. I do need help setting up authentication for users. That includes creating and managing accounts, as well as enforcing secure access to the NATS environment. An ideal Freelancer for this job should have prior experience working with NATS and setting up authentications. Looking forward to hearing from you!
