Worked on the major/ec2-plugin repository to enhance the reliability of EC2 operations in environments with rotating credentials. Developed a feature in Java that automatically reconnects when encountering ExpiredToken errors during credential expiry, extending the plugin’s existing RequestExpired handling. This approach improved the plugin’s resilience by reducing manual intervention and minimizing downtime caused by expired credentials. Updated logging mechanisms were introduced to provide clearer observability and facilitate faster troubleshooting of credential-related issues. Leveraged AWS and cloud computing expertise, along with error handling and Jenkins plugin development skills, to deliver a robust solution that strengthens credential management within the EC2 plugin.
