At American Express (Malaysia) Sdn Bhd, I integrated engineer-built APIs with CLIC to automate workflows for 300,000 customer accounts annually. I added structured data processing and automated quality checks, reducing operational errors to 0.01%.
I also analyzed customer and campaign data to support card upgrades and customer retention, and designed data-driven guidelines for late fee and interest waiver decisions. Earlier, I audited monthly incentive payouts for customer service representatives and prepared Singapore Business Update Reports using Power BI.
