Aminu Oluwarotimi

I’m a Data Analyst with 3+ years of experience and a civil engineering background. I use Excel, Python, and SQL to build predictive models, run statistical analysis, test hypotheses, and deliver clear, compelling visualizations.

In my current role, I spearhead data collection and validation across 20+ sources, improving data accuracy and reducing reporting time. I’ve built and maintained 15+ interactive Tableau and Power BI dashboards, and I leverage data mining and machine learning to uncover trends that improve project efficiency.

I also focus on automation and data quality: SQL/Python automation reduced manual intervention by 30%, while revamped validation and cleaning processes elevated data accuracy and consistency. I streamline data quality and governance protocols to boost predictive model performance and data integrity.

Beyond analytics, I’ve worked on survey and infrastructure data with digital collection tools (Kobo Collect, SurveyCTO) and contributed to data science work that includes ETL pipelines, KPI optimization, A/B testing, and data modeling. I enjoy collaborating with technical and non-technical stakeholders to turn data into actionable strategy.
