I will design star schema data warehouses and sql data modeling

Need a scalable, clean, and optimized Data Warehouse for your business analytics? I am here to help!

I specialize in designing relational and dimensional data models (Star Schema / Snowflake Schema) that optimize analytical queries and support historical tracking without data duplication.

Historical Data Tracking (SCD): Implementation of Slowly Changing Dimensions (SCD Type 1 & Type 2).

Advanced Analytical SQL: Writing CTEs, Window Functions (RANK, LAG, SUM OVER), triggers, and indexed views.

Query Performance Tuning: Indexing strategies and query optimization for fast reporting.

Data accuracy focused with clean, documented SQL scripts.

Fast turnarounds and clear communication.
