Samuel Reuben

I am a highly motivated and results-driven Data Analyst with a B.Sc. in Economics, specializing in leveraging the full analytics stack to transform complex data into strategic business intelligence. My core career focus is on designing and deploying end-to-end ETL data pipelines and developing high-impact, KPI-driven dashboards that actively support decision-making across finance, sales, and core business operations.

My technical proficiency spans key industry tools, including Python (Pandas, NumPy) for advanced data manipulation and feature engineering, Advanced SQL (MySQL, PostgreSQL) for robust querying and database optimization, and Power BI (DAX, Power Query) for modeling and visualization. I am passionate about data architecture, which is reflected in my ability to design scalable star-schema data models and develop complex formulas (15+ DAX measures) to ensure data integrity and query efficiency.

Key Achievements & Professional Interests:

• Clinical & Healthcare Analytics: I led the engineering of a synthetic multi-table EHR dataset and built interactive dashboards delivering real-time clinical trial insights, demonstrating my ability to handle complex, specialized data domains.

• Sales & Revenue Optimization: I have delivered projects with measurable financial impact, including a Sales and Revenue Analysis utilizing Power Query and Pivot Tables that generated $352K in Total Revenue and helped identify high-value customer segments and key revenue drivers.

• Strategic Insight Generation: My primary interest is in providing actionable insights by conducting in-depth segmentation and trend analysis to define high-value customer cohorts, which directly informs targeted marketing, loyalty, and subscription strategies.

• Data Leadership & Vision: I excel at managing analytical efforts from data ingestion and cleaning (Data Engineering) through to final modeling and visualization (Business Intelligence). I am committed to translating technical findings into clear, strategic recommendations, ensuring stakeholders are enabled with the real-time insights required to optimize performance and drive strategic advantage.
