At Vodafone Intelligent Solutions (VOIS), I cut missing-cell rates by 82% across 50,000+ records using automated quality checks and feature engineering in Python and SQL. I also streamlined reporting by building KPIs and reusable DAX measures in Power BI, and prototyped natural-language querying over structured data for business teams.
I independently shipped a live bankruptcy-risk screener that benchmarked six models and used cost-based risk alerts to reduce expected review cost by 25%. I’ve also analyzed UPI app reviews with the RICE framework and used customer shopping analysis to identify where acquisition, rather than discounts, warranted attention.
