Selumun Salome Aondoakaa

I’m a detail-oriented, results-driven Data Analyst with hands-on experience analyzing business data, developing interactive dashboards, and delivering actionable insights that improve operational performance and business decision-making.

I’ve used SQL, Power BI, and Advanced Excel to transform raw datasets into meaningful insights for KPI tracking, reporting automation, data visualization, and business intelligence—especially in manufacturing and retail environments.

At Shimao Sport Product, I built interactive Power BI dashboards to track sales performance, operational KPIs, customer trends, and revenue metrics, and improved reporting efficiency by 50% through automation of recurring analysis and reporting tasks. I also used SQL for querying, filtering, and analyzing data from multiple operational sources, and performed EDA to identify trends and anomalies.

Previously at Royal Castle Ceramics, I analyzed production, inventory, and sales datasets to identify operational trends, improving reporting accuracy by 15%. I developed automated Excel reporting systems that reduced manual workload by 40%, designed KPI dashboards using Excel and Power BI, and wrote SQL queries for extraction, cleaning, and analysis—while supporting cross-functional sales and operations teams with real-time reporting and performance tracking.
