Worked on the americanexpress/synapse repository to enhance backend security, dependency management, and platform stability over a three-month period. Delivered automated workflows using GitHub Actions and Python scripting to compare dependencies, flag downgrades, and generate upgrade summaries, improving auditability and risk detection. Upgraded Spring Boot and Spring Framework versions to address critical CVEs, aligning with security compliance requirements and reducing vulnerability exposure. Applied targeted dependency overrides in Maven to patch vulnerabilities in Apache Commons libraries, with clear documentation for future maintenance. Focused on secure deployment practices, disciplined patch management, and maintaining compatibility across modules using Java, Maven, and Spring technologies.
