I have a new project that needs a landing page, a signup flow, and a dashboard section displaying some data from a database.

I highly prefer simple, blazing fast websites like Hacker News and Craigslist that load near instantly.

I’ve got a little experience with Rails, React, Java/Kotlin (Android), and node/express.

Is there a particular tech stack that would be suitable for building something where load speed is a priority? I am more than happy to learn a new stack for this project. Thank you!
