What I'm looking for

I'm seeking a data analyst role where I can apply Power BI, Excel, SQL, and Python to drive financial insights, build dashboards, automate reporting, and support data-driven decision-making.

I am a detail-oriented Data Analyst who transforms raw datasets into actionable business insights using Power BI, Excel, SQL, and Python. At NSSF I managed and analyzed financial records, developed dashboards for trend analysis, cleaned and validated large datasets, and automated payroll and claims processes to improve accuracy and efficiency.

I enjoy bridging data and business strategy, providing audit and compliance teams with reliable insights, and building interactive dashboards and automation solutions. My projects—hosted on GitHub—showcase HR analytics, COVID-19 SQL analysis, and advanced Excel dashboards and formula work.
