K8s is complicated , but Docker (docker compose) solves a lot of problems especially when you are working with a team. Just 5-10 lines of YAML code in your docker-compose.yaml file and it gives you an local infrastructure of db , redis , node , python , nginx and many other things. Then you can share with anyone in your team , and it works on their machine too. Don't afraid of time saving tech.

We had use nodejs/ts , but nothing meets DX of python , or Python + MyPy yet, and ecosystem is unmatched.
