Indie Covid19 tracking website Cov19.xyz, created by an Italian CTO

Hi Makers! I thought some of the indie devs in here may find this COVID19 tracking platform, Cov19.xyz, a cool inspiration. I recently profiled the Cov19.xyz service and spoke to its creator to hear his process behind creating the service. (You can read that here: https://gen.xyz/l/gm) I'm curious if anyone else has experience creating a web-based platform with a quick turnaround time like this? Would love to hear about it below if you have!
