Hi, I'm Annelize 👋

Data analyst based in Germany, with a commercial law degree and 18+ years of legal and operations work behind me. I work AI-native with Claude Code, turning messy operational data into analysis-ready datasets and dashboards in SQL, Python and Power BI.

Start here

  • analog-heroes-analytics - my flagship: an invented Amazon seller, a DuckDB star schema backed by 39 automated tests, and a Power BI dashboard answering one question: which SKUs earn their FBA fees?
  • ml-car-price-prediction - does a manual ML workflow beat an automated one? Manual feature engineering vs PyCaret, interpreted with SHAP and LIME
  • nlp-disaster-tweets - TF-IDF text classification with an honest error analysis of where bag-of-words hits its ceiling
  • cv-cifar10-classification - transfer learning with ResNet50, including what confused the model and why

Most projects have a video walkthrough on my website.
