What I'm looking for

I'm seeking a Data Analyst, Junior Data Analyst, Data Analyst Intern, or Freelance Data Analyst role where I can apply my data analysis and spreadsheet skills.

My Excel projects cover business datasets involving sales, employees, products, payroll, inventory, student performance, and targets. I cleaned, organized, transformed, and analyzed the data, then structured worksheets for reporting.

For sales and performance analysis, I calculated totals, averages, targets, and performance indicators, organizing results by products, employees, periods, and business categories.

I also organized employee records and performed payroll-related calculations using logical, lookup, and date functions. My Excel work includes formulas such as IF, VLOOKUP, and date functions.

In my data and administrative work in Nigeria, I handled structured records, spreadsheet-based processing, and reporting support. I also completed data-related and administrative tasks for six clients, applying data-management skills to their requirements.
