Just use TypeScript frontend and backend. For backend, use Node+Express+TypeScript. If doing anything in ML, create a service in Python, but keep application code in TypeScript.

If you are doing full stack development, this works much better. The npm ecosystem is amazing. You can create common libs, share types, don't have to context switch and all future developers can do some full stack.

This is the boring stuff, but works and scales.
