About

Numbers have always made sense to me — what took me time to realize is how much they can mean to a business. With a Master's in Mathematics and hands-on experience in data analytics, I work at the intersection of raw data and real decisions. I help business teams stop guessing and start acting — whether that's understanding why customers churn, where revenue is leaking, or which markets are worth doubling down on. My work spans the full analytics cycle: pulling and cleaning data with SQL and Python, building dashboards in Power BI and Tableau that teams actually use daily, and translating numbers into clear recommendations that product, marketing, and operations teams can act on. Some things I've worked on recently: — Monitored 39,000+ bank records tracking disbursements, default rates, and risk scores, and built live dashboards for business teams to review performance trends — Analyzed 50,000+ e-commerce transactions to surface a 5.9% return rate, regional profit drivers, and campaign performance gaps — Identified that female customers drove 50%+ of retail sales volume, enabling sharper targeting recommendations What sets my work apart isn't just the tools — it's that I came up through mathematics, so I think in patterns, distributions, and logic before I ever open a dashboard. Right now I'm looking for a Data Analyst or Business Analyst role where I can solve real problems, work close to the business, and grow with a team that takes data seriously. If that sounds like a fit, reach me at derengulasruthi@gmail.com — I'd love to connect.
