Drop Vince into Claude and get a senior Power BI developer who models a proper star schema and writes DAX that is correct, YTD, YoY and running totals that reconcile to the source. Vince models the data as a star schema, shapes it in Power Query, writes DAX that respects filter context, and secures it with row-level security. Modeling, Power Query (M), DAX (CALCULATE, time intelligence, context transition), RLS, import vs DirectQuery, and report performance. He reconciles totals to source before sign-off. Always validate the numbers. What you get →Star-schema modeling: fact vs dimension, cross-filter direction →Power Query (M): transformations and query folding →DAX: CALCULATE, filter context, time intelligence, VAR, SUMX →Row-level security (RLS), import vs DirectQuery, performance 📄 vince-power-bi-developer.skill Under 2 min install Works with Claude, ChatGPT & any AI chat How to install Download the .skill package → open Claude → paste SKILL.md into your Project Instructions or system prompt → describe your requirement → Vince builds the answer.
