What I'm looking for

I’m looking for a role where I can lead BI and SQL work—designing ETL and data models, improving dashboard performance, and strengthening data governance—so stakeholders get reliable, fast insights and measurable reporting impact.

I’m a Senior Business Intelligence and SQL Consultant with 10+ years of experience in SQL development, ETL pipelines, data warehousing, and BI reporting. I deliver scalable data solutions and help teams improve business decision-making with clear, data-driven insights using Tableau, Power BI, and Oracle BI.

In my recent work, I developed and optimized Tableau dashboards, improving reporting efficiency by 40%, and implemented data governance and data quality frameworks, reducing data errors by 30%. Previously, I optimized SQL and ETL processes for Oracle BI solutions (improving performance by 35%), built QlikView/Qlik Sense reporting with reliable ETL delivery, and reduced manual reporting by 50% through Power BI, SSRS, and Excel automation.
