Senior🎓
Top SchoolMac Chiang is a Senior Audio Engineer with 11 years of embedded audio and Linux sound SoC development experience, currently based in Taoyuan City, Taiwan. He has deep expertise porting and tuning audio stacks—from AudioFlinger and ALSA up through codec drivers and acoustic DSP features like echo cancellation and noise suppression. His work spans smartphone platforms (Qualcomm, NVIDIA, MediaTek) and coreboot firmware contributions enabling I2S audio and Bluetooth offload on Google-related hardware, reflecting rare cross-domain skills in both firmware and Android audio layers. At Intel and Acer he led audio HAL/driver integration, CTS verification, and dynamic acoustic tuning tied to country-specific parameters. Proactive and cooperative by trait, he combines hands-on low-level engineering with system-level verification and telecom call-stack familiarity. An interesting detail: he architects solutions that adapt device acoustic profiles based on MCC/MNC codes, demonstrating attention to real-world deployment variability.
