Have you considering using anything like AWS or Heroku? I know you say in the article you want to keep it simple but services like those can hide this complexity for you and their solution is likely to be more robust. Also, if you're only using a single Digital Ocean droplet at the moment, you will have to consider the changes you'll need to make when you require more than one droplet or the droplet you're using goes down. Looks like a fun project; good luck!
