About Me / 关于我
I’m a .NET backend engineer, primarily working in the financial / trading systems domain. I enjoy turning reusable capabilities from day-to-day development into standalone open-source libraries — from low-level high-precision timers and health monitoring, to OS-level virtual disk drivers.
我是一名 .NET 后端工程师，日常主要在金融 / 交易系统领域工作。喜欢把开发中沉淀出的可复用能力做成独立的开源工具库——从底层的高精度计时器、健康监测，到操作系统层面的虚拟磁盘驱动，都是兴趣驱动的产出。
