PROFILE
Chien Chen
Worked on the Rytass/Utils repository to enhance payment processing reliability and compliance for NewebPay integrations. Over three months, delivered partial refund support with amount parameterization, enforced policy restrictions for installments and discounts, and improved state management and logging using TypeScript and backend development skills. Addressed edge cases in refund logic, implemented server-to-server notification for bind-card flows, and introduced idempotent event handling to prevent duplicate transactions. Hardened backend payment flows by explicitly setting User-Agent headers on API calls, resolving Akamai 403 errors. Comprehensive unit and integration tests validated new behaviors, reducing payment errors and improving overall checkout stability and reporting.
