What I'm looking for

I'm looking for a data-focused role where I can use Python, SQL, Excel, and Power BI to turn operational or business data into clear insights while continuing to grow in analytics and financial modelling.

I've analyzed student performance at Greater Grace Academy, helping contribute to a 15% improvement in academic results through assessment-trend visualization and tailored teaching methods. At Gomoa Community Bank PLC, I maintained daily reports with 100% data integrity and managed digital records for branch operations.

I'm studying Mathematics and Statistics at the University of Cape Coast and have built projects in Bitcoin ETF sentiment analysis, Netflix investigation, gold-price analysis, BMW sales analysis, and student academic performance. I use Python, SQL, advanced Excel, and Power BI/DAX to validate, transform, visualize, and communicate data.
