What I'm looking for

I'm looking for a data-focused role where I can apply Python, SQL, machine learning, forecasting, and visualisation to solve practical business problems, communicate clear insights, and continue developing with new tools and domains.

I've built 12 real-world data projects through TripleTen, including a taxi-demand forecasting model that achieved an RMSE of 42.60 and a used-car price model that improved 27.49% over baseline.

At Eiscafe Breda, I used weather, weekday, and seasonality data to forecast daily demand and support revenue and operational decisions. I also built advanced Excel models for KPI tracking, recipe scaling, and weighted tip distribution across 15 employees.

I work with Python, SQL, machine learning, statistical modelling, time series analysis, ETL pipelines, and data visualisation to turn large datasets into clear recommendations for technical and non-technical stakeholders.
