About

At Chygor-Cole Specialist Hospital, I manage records and maintain accurate documentation as an Administrative Assistant and Customer Support professional. I also assist with reports and customer enquiries. Previously, I worked as a Data Entry Officer at Chygor-Cole Specialist Hospital, entering and updating database records and reviewing data for errors or inconsistencies. For my sales performance dashboard project, I analyzed monthly sales data using Excel and Power BI. I created interactive dashboards to identify top-performing products and low-sales periods, improving reporting accuracy and the presentation of business insights. In my Customer Data Analysis project, I cleaned and organized customer datasets in Excel, used charts and pivot tables to identify trends, and presented the findings in a simple business report. I hold a Higher National Diploma and a National Diploma from Osun State College of Technology.
