Worked on improving repository hygiene for JetBrains/compose-hot-reload by updating the .gitignore to exclude local.properties, thereby preventing sensitive local configuration from being tracked in version control. This change, implemented using Git and Gradle, enhanced the security posture of the project and reduced the risk of accidental credential exposure. The update also streamlined the onboarding process for new developers by ensuring a cleaner and more reproducible local setup. Throughout the process, demonstrated skills in configuration management and version control, collaborating with team members to maintain best practices and support consistent, secure development workflows across different environments without introducing new bugs.
