Hello everybody,

I work at Quansight Labs and spend time on:

• Polars
• pandas
• assorted consluting / training

I've also written some assorted little tools:

• cython-lint (the world's first Cython linter?)
• absolufy-imports (superseded by ruff)
• nbQA (mostly superseded by ruff, but still gets ~100k downloads/month for some reason)
• auto-walrus (hopefully won't be implemented in ruff)
• polars-upgrade (the only way is up)
• polars-xdt (eXtra stuff for Dates 'n' Times)
• narwhals (🎵singing in the ocean, causing a commotion🎶)

and a tutorial on how to write Polars Plugins: https://marcogorelli.github.io/polars-plugins-tutorial/. Don't be scared
