I'm a Camera Driver Software Engineer based in Shanghai, China 🇨🇳.
I work across the full Android camera stack — from kernel-space drivers (V4L2, MIPI CSI/DSI, I2C/SPI sensor bring-up) to userspace HAL3 (CameraProvider, CameraDeviceSession, Request/Result metadata) and framework integration (Camera2 API, CameraX). My daily reality is bridging raw silicon behavior with the polished experience users expect: configuring ISP pipelines, tuning 3A algorithms (AE/AWB/AF), debugging frame drops through Perfetto traces, and shaving milliseconds off cold-start latency.
I've shipped camera features across multiple SoC platforms (Qualcomm, MediaTek, etc.) and dealt with the full lifecycle — from sensor driver bring-up and register-level debugging to HAL conformance testing and CTS/VTS pass. I care about things most developers never see: stream configuration combinations, metadata queue depth, reprocessing pipeline latency, and the difference between a 30ms and 32ms shutter-to-callback path.
Outside the kernel, I'm deeply invested in AI-augmented engineering — building LLM-powered dev workflows, local-first automation pipelines, and cost-efficient knowledge management systems. I believe the best toolchains are the ones nobody notices for 90 days straight.
"完美系统不存在，只有稳定三个月不动的系统。" There is no perfect system — only one that runs quietly for 90 days without anyone touching it.
