new tools
I’ve been back at work for three weeks after seven-and-a-half months of maternity leave, and it genuinely feels like I've returned to a completely different industry. The fundamentals haven't changed: data pipelines still break in unexpected ways, and tech debt still needs managing. But how

I've been using Jupyter notebooks for almost a decade to power everything from quick exploratory data analyses to end-to-end machine learning prototypes. While these notebooks have served their purpose, I'm sure that the majority of data scientists will agree that they also come with some headaches:
bigquery
BigQuery is powerful — but it can also be expensive and slow if you don’t know what you’re doing. It's easy to accidentally scan terabytes of data when you only meant to query a few gigabytes. Mistakes like these can end up costing hundreds (and sometimes thousands)

Let's dig into what DuckDB is and why there's so much hype around it.
After working with BigQuery for almost five years, here are five features that I wish I knew about earlier in my career.
I'm back from a one year hiatus and I'm excited to bring this blog back to life.
Let's learn how to handle large data with Pandas, Polars, and DuckDB.
