What technical skills should a Power BI developer possess?

Power BI developers should have a strong grasp of data modeling, DAX (Data Analysis Expressions), and Power Query for transforming data. Proficiency in SQL is crucial for querying databases, along with knowledge of database management systems like SQL Server or Oracle. Experience in data warehousing and ETL (Extract, Transform, Load) processes is beneficial for managing complex data sources. Additionally, familiarity with integrating Power BI with various data sources, including cloud platforms like Azure, and creating interactive dashboards and reports is essential. A solid foundation in these technical skills enables developers to build robust, scalable solutions.
