I rewrote a very slow backup lambda from Python, which I know well, to Scala, which I have done like three sections of the intro to scala exercises, in about 4 hours, totally vibe coding

Helped: Knowing Python well and skimming Scala code for sensibility.
I rewrote a very slow backup lambda from Python, which I know well, to Scala, which I have done like three sections of the intro to scala exercises, in about 4 hours, totally vibe coding, but I know enough to skim it and see it is doing things a sensible way, and to get error handling and retries in the robust way. (New job they use Python for slow stuff and Scala for higher performance things).
