Worked on the Adyen/adyen-node-api-library, focusing on backend development and API integration using TypeScript. Addressed a critical reliability issue by fixing the PossSDK Endpoint URL Prefix logic for possdk v68, ensuring that all requests consistently use the correct live endpoint URL prefix. This targeted bug fix improved the accuracy and reliability of API interactions by reducing endpoint-related errors. The work involved disciplined debugging and a clear, traceable commit history, reflecting a methodical approach to issue resolution. Throughout the month, maintained code quality and contributed to the stability of the library, emphasizing robust backend practices and precise API request handling.
