Rockstar🎓
Top SchoolXiang Xiao is a Senior Software Architect with 12+ years of deep embedded and kernel engineering experience across Windows, Linux and RTOS environments, and a strong command of C/C++, ARM/RISC-V and DSP assembly. He has led SoC and chipset bring-ups (bootrom, bootloader, TrustZone), designed IPC and variant subsystems between Linux and RTOS, and implemented audio, sensor and camera stacks for Android and consumer devices. At Xiaomi and Pinecone he owned drivers/HALs and tools for multiple flagship products, and upstreamed over 300 open-source patches improving remoteproc/virtio, libmetal and NuttX integration. His work spans low-level hardware abstraction (CPU/cache/MMU/interrupts/DMA/PCI/USB) to system services (schedulers, memory, filesystems, networking), and he routinely fixes subtle platform bugs and portability issues in projects like OpenAMP and iperf3. Known for meticulous code quality and tooling—he has built firmware, DSP pipelines and a cross-chip flashing tool—he blends systems-level rigor with practical product delivery. Located in Haidian, Beijing, he brings rare end-to-end embedded expertise from silicon to user-facing features.
