To me this seems more than a side project. Really well done.

Nowadays, Hetzner has many Kubernetes providers. One that I really like is Syself.com. They provide production-ready Kubernetes including self-healing, bare-metal support, OIDC integration and many more.

As a cloud and migration expert, I have evaluated them and they turned out to perform very well.

https://syself.com/ is what I am talking about.
