What I'm looking for

I’m looking for a role where I can build reliable BI solutions—Power BI dashboards, ETL pipelines, and SQL/DAX analysis—while partnering with stakeholders to deliver measurable business impact through strong data governance and clear communication.

I’m a Data Analyst and Power BI Developer who designs and maintains interactive dashboards and reports that turn complex data into actionable insights. I analyze large datasets with SQL, DAX, and Power Query (M), while building efficient data models and ETL processes that prioritize data quality, governance, and performance.

I partner with stakeholders to gather requirements and translate business needs into scalable analytics solutions, backed by thorough data validation. Along the way, I’ve optimized Tableau dashboards, embedded Power BI into SharePoint, supported ETL for datasets with 50K+ rows, improved member engagement by 10%, reduced operational costs by 10%, and increased report accessibility by 25%—while mentoring junior analysts to strengthen the team.
