Divine Onyema

I’m a highly analytical, results-driven Data Analyst & Educator with hands-on expertise in SQL, Power BI, advanced Excel modeling, and Tableau. I use data cleaning, dashboard-building, and workflow automation to translate complex datasets into actionable business infrastructure.

Recently, I founded and lead Data2Insight Hub (Data Analyst Girlie), moderating a community on X and hosting Saturday audio spaces focused on data automation, workflow optimization, and troubleshooting. I also develop structured YouTube tutorials and curriculum roadmaps to mentor both beginners and advanced learners globally.

In my Data & Research Analyst role at Onyema’s Agrochemicals, I designed and deployed a centralized relational sales database in MySQL, migrating legacy CSV inventory records and achieving 100% data integrity for financial reporting. I analyzed two years of transaction logs to uncover seasonal purchasing patterns, delivered gross profit margin insights for pricing recommendations, and used inventory turnover signals to flag slow-moving stock and reduce waste.

I’m equally energized by research-grade analytics and learning leadership. My Samsung market dynamics project used Power BI and Excel to map multi-year trends across territories, while my SaaS CLV and segmentation work combined SQL and Tableau to model cohort-based lifetime value and retention/churn timelines. I bring a deep academic foundation in Industrial Chemistry and a mentorship mindset from serving as a peer mentor and organizing learning orientations.
