What I'm looking for

I seek a data-focused role where I can build dashboards, automate ETL, ensure data quality, and drive strategic, analytic decisions in a collaborative environment.

I am a highly analytical data specialist with 4+ years of hands-on experience extracting, transforming, and visualizing large datasets to inform executive decision-making. I build and maintain interactive dashboards in Power BI and Tableau, apply statistical methods with Python and R, and implement ETL and data quality processes that measurably improve reporting accuracy and efficiency.

At Global Solutions Ltd. I executed complex SQL queries, developed 10+ Power BI dashboards that improved marketing targeting by 12%, automated ETL workflows to save weekly preparation time, and reduced reporting discrepancies by 25% through validation scripts and advanced Excel. I hold a BSc in Information Technology and certifications including Microsoft Certified: Data Analyst Associate.
