Senior Data Scientist at EXL building BigQuery experimentation and funnel analytics for a FTSE 100 UK retailer.

At EXL, I built a self-serve A/B testing dashboard and an eight-stage BigQuery pipeline used by trade teams across UK and international markets. I also created a feasibility calculator to show whether tests could reach significance before they run.

I designed the Session-Level Funnel codebase, turning GA4 events into 118 session flags used for reporting and experiment analysis. I also built a causal inference pipeline and detected bot fleets across 363 million sessions, with five auditable SQL rules and zero orders lost.

At O1Labs.ai, the AI products studio I founded, I built and launched Callytics, an AI debt-collection platform that lifted promise-to-pay conversion by 40% and automated RBI-compliance checks. I also delivered conversation analytics that raised client collections revenue by 25%.

Earlier, I architected Masai School's data platform and built a student-success prediction model. At Kin Insurance, BulBul, and Wheelseye, I applied data science and analytics to insurance, video commerce, and logistics problems.
