Worked on the keiyoushi/extensions-source repository to address a domain migration for the Hayalistic Extension, ensuring the application continued to communicate with the correct server after the domain changed from hayalistic.net to hayalistic.com. The update involved modifying the base URL within the Gradle build configuration and incrementing the version code to align with deployment practices. This fix improved server reliability and reduced the risk of misrouting or build-time errors. The work demonstrated proficiency in Android development, Kotlin, and Gradle, with clear, traceable commits and documentation that support release hygiene and facilitate future audits or rollbacks as needed.
