End-to-End Data Analytics: From Raw Data to Actionable InsightsUsamah W Maphumulo
I transform messy, unstructured data into clear, interactive dashboards that drive business decisions. I don’t just build charts; I ensure the underlying data is mathematically sound and strategically relevant.
My Workflow & Tech Stack
Data Cleaning & Inspection: I handle missing values, outliers, and structural errors using Pandas (Python) and SQL to ensure a "single source of truth."
Deep-Dive Analysis: I apply complex transformations and business logic using DAX and SQL to uncover hidden patterns and trends.
Exploratory Data Analysis (EDA): I inspect the data distribution and correlations to ensure the insights are statistically significant.
Professional Visualization: I deliver the final insights through high-performance dashboards in Power BI, Tableau, or Looker, customized to your brand and KPIs.
What You Get
Cleaned Datasets: Ready-to-use data in your preferred format.
Interactive Dashboards: Fully filtered reports for real-time monitoring.
Actionable Insights: A summary of what the data actually means for your growth.
Optimized Queries: Efficient SQL/DAX code that scales with your business.
Why Work With Me?
I bridge the gap between technical data science and business strategy. Whether it’s customer behavior, sales forecasting, or marketing attribution, I provide the clarity you need to move forward with confidence.
