After about a month of work and slimming down what I wanted to release, I finished the MVP. This included the public-facing website (static site), API (GraphQL), and app website (React). The only integration at this point would be Salesforce but I added some future ideas for integrations on the public site.
I decided to launch the MVP on DigitalOcean using their new Kubernetes product as well as take advantage of some of their newer products like the managed database. Overall it worked well and hasn't had too much downtime.
