On Pulse, I analyzed 2.76M e-commerce events with PostgreSQL and Amplitude, identifying where shoppers dropped out of the funnel and which categories lagged in cart-to-purchase conversion. I defined a north-star metric, built weekly retention cohorts, and recommended addressing cart friction first.
For ExperimentLab, I analyzed an A/B test across 588,101 users and built an Excel model, power planner, and decision memo; I also flagged unequal exposure profiles and recommended verifying randomization before scaling. For LoanLeads, I analyzed 125K telemarketing calls and developed a call-cap simulator and pre-call lead score. At L&T Finance, I tracked sales KPIs and quota attainment, contributing to a 15% increase in quota attainment and a 35% improvement in team sales productivity.
