If you're interested, this is how TimeTagger is built:
The TimeTagger backend runs on servers provided by Upcloud, in a datacenter in Amsterdam. The VM runs Ubuntu Linux; Docker is used to create a consistent environment between testing and deployment. Traefik is used as a load balancer and reverse proxy. Both are managed by MyPaas, which also handles deployments. The server software is implemented in Python, using the lightning-fast Uvicorn ASGI server with Asgineer on top.
