During July 2025, Daniel Carvalho focused on dependency management for the stone-payments/demo-sdk-android repository, upgrading the Stone SDK from version 4.11.1 to 4.11.5 using Gradle. This work centered on maintaining stability and ensuring compatibility with the latest SDK improvements, without introducing any functional changes or user-facing features. By proactively updating dependencies, Daniel reduced technical debt and positioned the codebase for smoother future enhancements. His approach emphasized maintainability and long-term reliability, leveraging skills in Gradle and Android SDK integration. The update provided a stable foundation for upcoming development, reflecting a methodical and forward-looking engineering mindset throughout the maintenance process.
