How to become a BI Developer
Overview
Design, build, and maintain business intelligence solutions — dashboards, semantic layers, and reports — that turn raw data into actionable insights.
Data-driven decision-making is a competitive necessity, and the demand for clean, reliable dashboards that business users actually trust continues to grow.
What AI changes
What AI accelerates
Writing SQL queries, generating chart recommendations, formatting dashboard layouts, scheduling report refreshes.
What stays human
Designing the semantic layer, defining business logic and metric calculations, interpreting stakeholder requirements, validating data accuracy.
AI generates dashboard layouts and writes SQL — your semantic layer design, data model decisions, and ability to translate business questions into metric definitions get more valuable, not less.
Day to day
Design and maintain data models in BI tools, write and optimise SQL queries, build dashboards, gather reporting requirements, schedule data refreshes.
