PROFILE
Vibhor Mahajan
Worked on the Samsung/TizenRT repository, delivering targeted enhancements to the media framework by implementing per-stream volume control, focus management, and persistent audio settings using JSON. Addressed real-time audio processing challenges by refining SPI transfer logic and improving notification handling in the Syntiant NDP120 driver, which reduced latency and increased stability. Integrated the cJSON library into the kernel build system to enable in-kernel JSON parsing, resolving build errors and laying the foundation for future configuration features. Demonstrated strong skills in C and C++ programming, embedded systems, and audio management, with a focus on robust engineering practices and maintainable code integration.

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.
