Geez … the job search grind here in Australia is really wearing me down :/ 14 months now and still nothing. I’ve stopped counting the number of applications submitted because it’s a ridiculous number. Had a handful of interviews but no luck.
Anyone else experiencing the same?

We've all seen dataframe spaghetti code out there.
But the remedy ... is pretty easy: just start using the pipe method!
The moment you see the `.pipe()` in action, you'll never want to write pipelines without it. See the reason why here:

The uv build backend is now stable, and considered ready for production use.
An alternative to setuptools, hatchling, etc. for pure Python projects, with a focus on good defaults, user-friendly error messages, and performance.
When used with uv, it's 10-35x faster.
