I'm interested in building myself a little web app. That's probably a simple task for most people here, but unfortunately when I left the world of web development jQuery was still considered 'pretty neat'.

So sell me your dream tech stack and tell me why I should build my web app with it.

For some background into the project:

• A Platform-as-a-service for another of my side projects
• Will need to interface into Digital Ocean's API to start and stop servers on the fly
• Will open up to a moderately simple dashboard page showing current resources and deployments
• Will need to have various step-by-step wizards for creating deployments
• Will need to be able to authenticate users, possibly with 2FA in the future
• Will need to interface with some form of payment provider (bonus points for recommendations!)

And background on myself:

• Primarily a C# developer
• Secondarily Python and Java
• Some experience with devops
• Some HTML, JS & CSS experience
• Lots of relational database experience
• Some NoSQL experience (specifically Firebase)

I look forward to reading any suggestions and recommendations people have! Feel free to ask for any more details etc. if you want!
