Worked on the Samsung/TizenRT repository to enhance embedded audio management by implementing per-stream volume control, focus management, and persistent user settings. Leveraged C and C++ to introduce JSON-based storage for audio preferences, ensuring consistent volume levels across sessions and enforcing focus requests before playback to prevent audio conflicts. Addressed build system challenges by integrating the cJSON library directly into the kernel binary, resolving undefined reference errors and enabling future JSON-driven configuration within the kernel. Demonstrated expertise in embedded systems, file I/O, and media frameworks, delivering robust solutions that improved audio routing, device management, and build reliability in a production environment.

Jul 1, 2025July 2025 monthly summary for Samsung/TizenRT focused on stabilizing and enabling in-kernel JSON handling by integrating the cJSON library into the kernel binary. The work addresses undefined reference errors and prepares the kernel for JSON usage, with initial changes committed to add cJSON to the kernel binary (commit f0eba1da155cf0ff07d15ad22a21dca69a8304e5). Integration is currently in progress but already reduces build-time symbol errors and aligns with existing Make.defs/build conventions, laying the groundwork for future JSON-driven configuration and data exchange within the kernel.

Nov 1, 2024November 2024: Delivered a targeted Media Framework enhancement in Samsung/TizenRT, implementing per-stream volume control, focus management, and volume persistence. Added JSON-based persistence for per-stream volume settings to maintain user preferences across sessions and enforced focus requests before playback to prevent conflicts, improving audio routing and device management. The work demonstrates strong embedded audio design, configuration persistence, and focus-management capabilities with tangible business value.
