About Me

Erika Enemenaye

I’m a Data Analyst and a graduate of Production Engineering, with expertise in transforming complex datasets into actionable insights. My work focuses on creating interactive visualizations and data-driven stories that help organizations make informed, data-backed decisions.

With experience in Power BI, SQL, Excel, and data modeling, I specialize in developing comprehensive reports and dashboards that uncover patterns, trends, and opportunities within data. This portfolio showcases projects across different areas, demonstrating my ability to turn raw data into meaningful business insights.

Beyond my personal projects, I’m passionate about helping others develop their data skills. I have also tutored students on Power BI visualization for free, guiding them through the process of transforming data into clear, interactive, and insightful dashboards.

My Projects

Project One Preview

RFM Analysis & Customer Segmentation

This project used RFM analysis and customer segmentation to evaluate purchasing behavior and identify customers based on their recency, frequency, and monetary value. Using Excel, Power Query, and Power BI, I cleaned and analyzed the data and built an interactive dashboard.

Key insights showed a 2–7% month-over-month sales decline and identified 30 at-risk customers, highlighting the need for targeted customer retention strategies.

Project Two Preview

TradeZone E-Commerce

This project analyzes TradeZone's 2023–2024 data using PostgreSQL to uncover insights around customer acquisition, product performance, seller fulfilment, revenue trends, customer spending, payment preferences and seller performance.

Tool used: SQL for data querying and analysis. Key insights revealed strong revenue growth (Q1 2023–Q4 2024), a small High Spender segment driving the majority of revenue
