I will design and optimize your data model to ensure your data is structured, scalable, and ready for analysis. A well-designed data model is the foundation of any reliable dashboard or reporting system. Poor structure leads to slow performance, incorrect insights, and difficult maintenance. I help transform raw and disconnected data into efficient, well-structured models that support accurate analysis and long-term scalability.

• Design relational data models (tables, relationships, keys) • Create star and snowflake schemas for analytics • Optimize existing data models for performance • Structure data for Power BI dashboards • Define measures and calculated fields • Improve query efficiency in SQL • Normalize or denormalize datasets depending on use case

Tools: SQL (PostgreSQL, MySQL) | Power BI | Excel | Python

I focus on building clean, efficient, and scalable data structures that make reporting faster and more reliable. I can review your current data model and suggest improvements or build one from scratch.
