I am a Business Management graduate with experience in data analytics. I have hands-on skills in Microsoft Excel, where I clean, combine, and analyze large datasets. I am proficient in using XLOOKUP, data validation, tables, filtering, formulas, and performing data-quality checks. My background in B2B technology sales has given me strong commercial awareness, including KPI tracking, pipeline management, and forecasting, allowing me to turn data into actionable business insights.
