BI & Dashboards

Builds Tableau dashboards that compute correct numbers at the right grain and stay fast - LOD expressions, filter-order pipeline, extract strategy, and mark-count control. Use when someone asks "why is my Tableau number different from SQL", "FIXED vs INCLUDE vs EXCLUDE", "my dashboard takes 30 seconds to load", "table calc or LOD", or is designing a workbook others will consume. Do NOT use for Power BI or DAX measures - use power-bi-dax instead; for narrative presentation of findings use data-story; for KPI selection and review cadence use kpi-scoreboard-and-cadence; for static table layout and formatting use data-table-design.

Turns SQL query results into a decision-ready business narrative - headline finding, drivers, recommendation - plus the right chart choice for the data shape. Use when someone asks "what does this data actually mean", "summarize these query results for the exec team", "what chart should I use for this", or pastes a result set and wants the so-what for a non-technical audience. Do NOT use to diagnose or speed up the query itself - use sql-query-optimizer instead; do NOT use to build a full multi-part narrative presentation around an analysis - use data-story instead; do NOT use for open-ended exploration of an unfamiliar dataset - use eda-playbook instead.

Turns data and charts into a decision-driving narrative structured as headline finding, trend, implication, and recommended action - with finding-led chart titles, context for every number, annotation guidance, and honest flags on any conclusion the data cannot support. Use when someone says "turn these numbers into a story", "what's the takeaway from this data", "help me present these results to leadership", or has charts but no narrative. Do NOT use for compressing a long document into a one-pager - use executive-summary instead - or for running the analysis that produces the findings - use eda-playbook instead.
