Over a two-month period, Mfge upgraded the Java Authentication & Authorization Library in the amzn/selling-partner-api-models repository, focusing on security and maintainability. They migrated the Auth&Auth Java client from com.squareup.okhttp to okhttp3, refactoring API client methods and updating internal API calls to align with the new library. Deprecated SSL configuration options were removed, reducing technical debt and hardening the security posture. Mfge also updated documentation to reflect these changes, ensuring clarity for downstream developers. Their work demonstrated strong skills in Java, API client development, and dependency management, delivering a modernized, more secure integration for the Selling Partner API.

Jan 1, 2025January 2025 – amzn/selling-partner-api-models: Delivered a security-focused modernization of the Java A&A library. Upgraded the Java Authentication & Authorization Library from com.squareup.okhttp to okhttp3 (v3.0), including updates to imports, method signatures, and internal API calls to align with the newer client. Removed deprecated SSL-related methods/configurations from ApiClient to harden security and reduce surface area. No major defects reported this month; work directly enhances compatibility with current Java HTTP stacks and positions the repo for future dependency updates. Business value: stronger security posture, improved maintainability, reduced risk of SSL-related regressions, and a smoother upgrade path for downstream services using the SP API models. Technologies/skills demonstrated: Java, okhttp3, API client modernization, SSL hardening, dependency management, code maintainability.
