What I'm looking for

I seek a data or analytics role where I can apply Excel, Power BI and SQL to automate reporting, improve data accuracy, and support data-driven decisions in a collaborative environment.

I am a data-focused professional with hands-on experience in cleaning, structuring, and automating reporting for large datasets, and a track record of improving operational efficiency and reporting accuracy. I have managed student records with 100% data accuracy, built Power BI dashboards from 500K+ row datasets, and automated reporting processes that saved teams 10+ hours weekly.

I combine technical skills in Excel, Power BI, SQL and Python with strong attention to detail, confidentiality, and effective communication to deliver actionable insights and streamlined workflows. I hold a BSc in Economics and recent certifications in data entry and data analytics that support my practical project work in RFM analysis and global sales performance dashboards.
