Data Analyst turning complex datasets into decisions—dashboards, models, and stakeholder-ready reporting.
What I'm looking for
I’m a results-driven Data Analyst with 5+ years turning complex datasets into decisions that stick. I specialize in SQL, Python, Power BI, and advanced Excel to deliver dashboards, statistical models, and reports that meet international standards.
In my most recent role, I cleaned and transformed 10,000+ records with Excel and Power BI, cutting data errors by 40% and reducing report turnaround from 3 days to under 1 day. I also built interactive Power BI dashboards tracking 5 KPIs weekly, alongside a data validation framework adopted as a team standard.
Earlier, I used Python (Pandas) to analyze community engagement across 12 programme areas, pinpointing 3 under-resourced sectors and supporting targeted reallocation. I delivered concise outputs for non-technical stakeholders while maintaining 100% NYSC reporting compliance across submission cycles.
Before that, I worked as a Research Analyst, using SPSS and Excel to contribute to 4 published research outputs with policy recommendations, including survey design and administration for 500+ participants. I bring that same rigor to projects like PayFast (A/B testing and activation lift) and logistics/hospital analytics where I diagnose conversion issues and revenue losses using Python, SQL, Jupyter, BigQuery, and Matplotlib.
