Worked on expanding AWS EC2 compatibility within the Jenkinsci/ec2-plugin by extending the InstanceTypeCompat component to support a broader range of EC2 instance types. This enhancement allowed users to configure additional AWS EC2 options directly through the plugin, improving flexibility for diverse deployment needs. The work involved Java-based plugin development, focusing on maintainable code and collaborative practices to ensure seamless integration with existing plugin architecture. No bug fixes were recorded during this period, with efforts concentrated on delivering this new feature. The approach emphasized clear code structure and alignment with AWS standards, supporting ongoing maintainability and extensibility of the plugin.
