2025 stack check: which DS/ML tools am I missing?

Hi all,

I work in ad-tech, where my job is to improve the product with data-driven algorithms, mostly on tabular datasets (CTR models, bidding, attribution, the usual).

Current work stack (quite classic I guess)

• pandas, numpy, scikit-learn, xgboost, statsmodels
• PyTorch (light use)
• JupyterLab & notebooks
• matplotlib, seaborn, plotly for viz
• Infra: everything runs on AWS (code is hosted on Github)

The news cycle is overflowing with LLM tools, I do use ChatGPT / Claude / Aider as helpers, but my main concern right now is the core DS/ML tooling that powers production pipelines.

So,
What genuinely awesome 2024-25 libraries, frameworks, or services should I try, so I don’t get left behind? 🙂
Any recommendations greatly appreciated, thanks!
