01 — About

A senior data professional, end to end.

I'm a Senior Data Analyst and Business Intelligence Developer with over five years of specialized experience transforming complex data into actionable business insights. My background spans government, insurance, telecommunications, and construction — giving me a broad understanding of how data-driven decisions shape performance across very different organizations.

My core expertise lies in designing interactive dashboards and analytical reports with Power BI and DAX, building end-to-end data pipelines with SQL (Oracle, SQL Server, Teradata), and applying Python for statistical analysis, data mining, and machine learning (Scikit-learn, TensorFlow, Keras, Pandas, NumPy). I have a strong track record of helping business departments interpret data, identify trends, and translate findings into clear recommendations for senior stakeholders.
