How I make a podcast website using serverless technology in 2023

In 2022, I launched a Kotlin podcast show, Kotlin Fireside Chat, with my friends in Kotlin User Group. Now, we're taking things to the next level by building a podcast website with a statistical analysis dashboard. We've built a static website using Jamstack and connected it to a serverless API written in Kotlin. In order to aggregate the listener number across platforms, such as YouTube, BiliBili, Ximalaya, Lizhi, Qingting, we've also created a crawler to grab those numbers and display them in a custom dashboard.
