Hi! For those not familiar, this app is built using Anvil (https://anvil.works), a platform for building full-stack web apps with nothing but Python.

It's got a visual UI designer, a built-in database, and you code everything in Python (even the client-side code). As you can see from this demo/tutorial, you can get things done pretty fast with it. I'm one of the founders, and that's my voice you're hearing on the video; I'm happy to answer questions!

(PS: We're hiring - https://anvil.works/jobs)
