I am a results-driven Data Analyst and Machine Learning Practitioner with experience in risk intelligence, business analytics, dashboard development, predictive modeling, and data science training.

I transform large, unstructured, and multi-source datasets into clean, structured, decision-ready intelligence. My work includes data validation, incident analysis, trend identification, reporting automation, and communicating insights to support business and risk decisions.

I am proficient in Python, SQL, Power BI, Tableau, Excel, Power Query, and DAX. I use these capabilities to develop dashboards, automate recurring reporting workflows, perform statistical analysis, and build machine learning models.

In my current risk intelligence role, I analyze security and safety incidents across Nigeria, maintain risk datasets, verify source information, and produce weekly, monthly, and quarterly intelligence reports. I work with high-volume incident records and identify geographic hotspots, emerging threats, and changing risk patterns.

I also have experience delivering analytics and machine learning training. I mentor learners in Data Analysis, Data Science, SQL, Excel, Power BI, Python, and machine learning concepts including regression, classification, clustering, and model evaluation.

I bring a practical, detail-oriented approach to data quality, predictive analytics, business intelligence, and stakeholder-ready insight presentation. I am motivated by using data to improve operational efficiency, business performance, and evidence-based decision-making.
