January 2026 focused on cross-platform API consistency and code hygiene across Android and iOS, delivering substantial refactors that align naming conventions with the companion platform, improve session handling visibility, and tighten public API surfaces. The work reduces onboarding friction and sets a solid foundation for platform parity and merchant integration. Key platform updates: - Android: Cross-Platform Naming Consistency and Session API Refactor to align with iOS conventions, including renaming initialize to setup, checkoutConfiguration to configuration, sessionModel to sessionResponse, and related session handling improvements. Public API clarity and code style improvements in SessionInteractor also completed. - iOS: Checkout API Naming Cleanup, renaming AdyenCheckout to Checkout across codebase, removing Adyen prefixes from related types and protocols, and updating file names accordingly. - iOS: ThreeDS2SdkVersion exposure and organization, making the constant public and adjusting file placement with a move and revert to preserve stability. Impact: API surface is now clearer and more consistent across platforms, reducing integration complexity for merchants and accelerating future parity work. Maintains a clean codebase with improved maintainability and testability. Technologies/skills demonstrated: Kotlin/Android and Swift/iOS naming conventions, public API design, code refactoring, file/structure organization, and commit hygiene across teams.
