IndiaWhat I'm looking for
At StockX, I diagnose platform transaction anomalies and resolve payment processing errors, payout bottlenecks, disputes, and buyer/seller discrepancies across Adyen, Braintree, Citcon, and Hyperwallet.
I use Riskified to assess transaction risk, investigate chargebacks, and identify account takeover indicators while minimizing false positives. I also track high-severity incidents and cross-tier escalations in Salesforce CRM and ServiceNow, partnering with Risk, Payments, and Compliance engineering teams.
Previously at Amazon Development Centre, I investigated complex customer complaints, legal and regulatory escalations, and improved average resolution time by 20% through streamlined root-cause investigation protocols.
I bring experience across phone, email, and live-chat support, with a focus on accurate documentation, SLA compliance, customer satisfaction, and continuous service improvement.
