PROFILE
Jeongkeun Kim
Worked on the ossrs/ffmpeg-webrtc repository to deliver AArch64 NEON optimizations targeting real-time audio and video processing on ARM platforms. Focused on low-level programming in C and Assembly, the developer implemented NEON-accelerated 32x32 SAD and DCA LFE FIR filter routines, achieving measurable speedups over scalar code paths. These optimizations were benchmarked on AWS Graviton3 hardware, demonstrating reduced compute cycles for critical WebRTC processing tasks. By aligning ARM NEON implementations with existing x86 SIMD routines, the work closed performance gaps and improved throughput for WebRTC pipelines, showcasing expertise in NEON intrinsics, performance optimization, and audio processing at the system level.
