I have a keen interest in data analytics, especially in technology and healthcare. I specialize in building dynamic dashboards and scalable data models using Power BI and Power Query. I also excel in writing optimized SQL queries that improve report performance and reduce refresh times, and leverage advanced DAX for complex calculations and analysis.

I believe BI isn't just about dashboards. It's about asking the right questions, challenging assumptions, and creating clarity from complexity. In healthcare particularly, analytical work carries weight. Before presenting insights, I validate data quality and assess what's actually in the dataset, because presenting misleading conclusions, even unintentionally, can influence decisions that matter.
