Oluwafemi Taiwo

I’m a detail-oriented aspiring Data Analyst with a Higher National Diploma in Health Information Management. I combine SQL, Power BI, and Excel to analyze large, real-world datasets and convert findings into dashboards and decision-ready insights.

In my projects, I built end-to-end analytics pipelines, relational data models, and executive dashboards. Using MySQL and Power BI, I analyzed 27,000+ clinical patient records and created a Star Schema model with DAX measures for clinical KPIs, including an average length of stay metric.

I also engineered a multi-platform e-commerce analytics pipeline (Maven Fuzzy Factory) to handle 1.7 million rows of web traffic and transaction data. I bulk-loaded data into MySQL, created pre-aggregated SQL views for efficient querying, and delivered a Power BI dashboard tracking revenue run-rates and channel performance, including a 6.83% storefront conversion rate insight.

I’m skilled in data cleaning, validation, deduplication, and KPI development—always focused on quality and clarity. With a Google Data Analytics Professional Certificate and additional Power BI and Excel training, I aim to build reliable reporting that non-technical stakeholders can trust and use.
