Worked on the Samsung/TizenFX repository over a two-month period, focusing on Smartcard API maintenance and reliability. Led the deprecation of the Tizen.Network.Smartcard API by systematically applying the [Obsolete] attribute to all related classes and methods, providing clear migration guidance for downstream developers and aligning with modernization goals. Addressed a critical memory management issue by replacing Interop.Libc.Free with Marshal.FreeHGlobal in SmartcardManagerImpl.cs, ensuring proper managed memory deallocation and reducing the risk of native memory leaks. Demonstrated expertise in C#, .NET interop, and Tizen development, contributing to improved code health, maintainability, and long-term stability of the platform.

Sep 1, 2025September 2025 (2025-09) focused on API maintenance and deprecation readiness. Key deliverable: Deprecate the Smartcard API in TizenFX by marking all Tizen.Network.Smartcard classes/methods with [Obsolete], signaling removal in future releases. Implemented via commit 48258f7ffe48b7221654cc97946c38814b7480c8 and linked to [TCSACR-622][Tizen.Network.Smartcard] Deprecate Smartcard API (#7175). No major bug fixes were reported this month. Business impact: reduces ongoing maintenance burden, clarifies migration path for downstream developers, and aligns the codebase with modernization goals. Technologies/skills: C#, .NET attributes, API deprecation strategy, versioning, and code-review discipline.
