Skills

The toolkit, mapped as a network.

Data Analytics & BI is the core. Data engineering is what keeps it trustworthy, and Generative AI is what extends it. The skills in the middle — Python, SQL Server, Microsoft Fabric, star-schema modelling — are the bridges that let one person own all three.

The same map, by role.

Machine learning is listed on its own rather than folded into BI — the data-science background stands separately from the reporting work, even though the two meet in every forecast.

Need a specific combination of these?

Most real projects pull from more than one column — that's the point of the overlap. Let's talk about what yours needs.
