I build analytics models and reporting tools through Self-Employed / Independent Projects, supporting quantitative tracking for operational clients. I also audit data quality and visualizations to address bias, misaligned scales, and unclear metric reporting.
For a Consumer Price Index analysis model, I worked with longitudinal datasets to evaluate economic and inflationary trends. I resolved data inconsistencies, null values, and scaling irregularities before creating Power BI dashboards with moving averages and multi-axis trend charts.
For the California Telecom Retention Audit, I analyzed customer data to identify churn indicators and wrote SQL queries to aggregate usage, payment tiers, and time-series history. I created interactive Tableau visualizations and documented the analytical methods in an open-access GitHub repository.
