In my M-Pesa Agent Assistant role, I process customer transactions and maintain and check transaction records and balances. I verify transaction details and follow procedures for secure, accurate financial transactions.

For my Sales Performance Analysis project, I analyzed 100 sales records and calculated KPIs including total sales, completed sales, orders, average order value, and quantity sold. I developed an Excel dashboard with KPI cards, charts, and business insights.

In my Data Cleaning & Quality project, I used Excel and Power Query to identify and correct data issues such as duplicate IDs, missing values, and inconsistent entries. I created quality checks and documented the problems and corrective actions.

I also analyzed operational order data across departments and regions, calculated completion, pending, and cancellation rates, and developed an operational KPI dashboard. I'm currently pursuing the Google Data Analytics Professional Certificate, with expected completion in December 2026.
