Ik maak je data snel schoon en visualiseer ze in Excel of Python

I'm Kashif, a data scientist working in Python, SQL and Excel. I build prediction models for churn, forecasting and classification, clean up messy datasets, and turn them into reports non-technical people can use. In three years I've delivered customer behaviour analysis, predictive modelling and reporting automation, including a pipeline that cut a client's reporting time by 40%. You get commented code, a plain-English summary of what the numbers mean, and an honest read on what your data can and can't support. Send me your dataset and your goal and I'll tell you what's realistic.
