I’m a data analyst turning datasets into actionable business insights using Excel, SQL, Power BI, and Python.
NigeriaWhat I'm looking for
I’m a results-driven Data Analyst with 3+ years of experience transforming complex datasets into actionable business insights. I’m proficient in Excel, SQL, Power BI, Tableau, and Python, and I focus on data modeling, dashboard development, and performance optimization.
In my recent roles, I’ve improved data quality and reporting efficiency—using Excel forms and validation to reduce entry errors by 90%, and building structured 3,000+ datasets in Power BI with star schema to improve scalability and performance. I also drive measurable outcomes by analyzing customer, booking, and operational data to reduce marketing costs by 25% and improve property turnaround time by 15%.
I enjoy turning messy information into clear decisions through automation and stakeholder communication. From collecting and cleaning 1,500+ records with Excel and SQL to reducing reporting time by 40% with Power BI dashboards, I’ve built a consistent track record of enabling data-driven decision-making and continuous learning.
