Worked on enhancing wallet import workflows for the vultisig/vultisig-ios and vultisig/vultisig-android repositories, focusing on improving testability and cross-platform consistency. Implemented support for importing .txt files and standardized file naming conventions, enabling more realistic and efficient testing scenarios on both iOS and Android platforms. Leveraged Swift and Kotlin to broaden input handling and streamline file validation, reducing manual setup for end-to-end validation. These updates established parity in test data handling across platforms and laid the foundation for future expansion of import formats. The work demonstrated depth in Android and iOS development, with a strong emphasis on file handling.
