• Develop star and snowflake schemas, including fact tables, dimension tables, hierarchies, keys, and relationships.
• Work with enterprise data warehouses, data marts, operational data stores, and cloud-based data platforms.
• Define appropriate model granularity, aggregation strategies, relationship behaviour, and data-access patterns.
• Assist with modernizing legacy cubes and reporting models into Power BI or modern tabular semantic models.
• Ensure semantic models maintain consistent business definitions across reports and consuming applications.
• Maintain clear data lineage between source systems, data-transformation layers, semantic models, and reports.

• Analyze slow-running reports and queries and identify model, DAX, storage, or source-system bottlenecks.
• Improve model performance through appropriate schema design, cardinality management, aggregations, partitioning, incremental refresh, and efficient calculation logic.
• Optimize SQL queries, stored procedures, views, indexes, and data-extraction processes supporting semantic models.
• Monitor model size, refresh duration, query response time, capacity usage, and report performance.
