Data, Business Intelligence & Reporting
Hi, I’m Kosi Chiemerie.
Data Analyst | Business Intelligence Analyst | Reporting Analyst
I use Excel, SQL and Power BI to clean, analyze and organize data, answer business questions, and find patterns and useful information that may not be obvious at first. I then present the findings through clear reports and dashboards so decision-makers can understand what is happening, see what needs attention and make better business decisions.
About
Clear data. Useful reporting. Better decisions.
My approach to analytics is simple: make sure the data is accurate, understand what the numbers are saying, and present the information in a way that is easy to follow. I enjoy working through data, finding what matters, and turning it into reports and dashboards that help decision-makers quickly see what is happening and what needs attention. Through my education and project work, I have built practical skills in data cleaning, analysis, business intelligence and reporting.
