Freelance Job: DevOps for Stock Market Application

Hi. We have a big project in US Stocks, and we want you on board.
We're looking for expert devops to help us deploy our app to DigitalOcean.
We have work for years... and we're looking for people to join us in the long term - please only contact us if you can handle a lot of hard work and you're expert in devops.

About us and our needs... we have a React Dashboard that fetches backend endpoints (connected to a MongoDB and Redis databases) and a websocket (that works with Redis pub/sub), and we want to deploy everything to DigitalOcean.

Please explain to us how you would set this up on DigitalOcean and explain everything in detail.
Also feel free to propose smarter solutions to what we're doing .

Thanks !
