What I'm looking for

I'm looking for a data analytics role where I can use Excel, SQL, and Power BI to improve reporting, strengthen data quality, deliver actionable insights, and support performance monitoring, forecasting, and risk mitigation.

At Aptech, I analyzed large financial and operational datasets using Excel and SQL, helping improve data accuracy while reducing manual analysis effort.

I designed and automated interactive Power BI dashboards and management reports that improved KPI visibility and reporting efficiency. My work includes cleaning, validating, and reconciling data across multiple sources to strengthen reporting reliability.

I conduct trend, variance, and risk analysis to uncover performance gaps, anomalies, and decision-ready insights for management and stakeholders.

I also built an interactive Power BI dashboard analyzing sales, costs, revenue, and profit across products, regions, and time, identifying top-performing products, profit drivers, and sales patterns.
