What I'm looking for

I’m looking to lead end-to-end payment fraud programs—signal discovery, rule design, decisioning, and incident response—using SQL/Python to cut BPS and losses while protecting customer experience in a fast-moving fintech.

I’m a fraud risk professional with 8 years of experience across crypto, digital wallets, and fintech, specializing in end-to-end fraud strategy—from signal discovery and rule design to decisioning engine deployment and cross-functional incident management. At Coinbase, I’ve reduced CX contact rates by 75%, BPS by 70%, and large loss events by 90% across Australia Push Payments, while keeping guardrails tight (e.g., maintaining BPS below 30 BPS for Netherlands iDEAL).

I lead high-impact investigations and RCA, including identifying an IDV clustering flaw that exposed 350K unclassified fraudulent users across a 6.5M active user base, then driving the remediation through engineering, DS, and product. Previously at MobiKwik, I scaled revenue from 1B INR to 5B INR while improving loss rate from 20% to 10%, and I saved 60M INR monthly via merchant fraud detection and improved collections outcomes through data-driven prioritization.
