Platform & Full-Stack Engineer平台与全栈工程师

Liu Tianyi

I build the platforms that make low-level engineering scale — turning slow, manual, system-level work like driver builds, firmware tests, and crash analysis into automated tooling across the whole stack. Folding AI into the workflow is a strength of mine, too: with AI in the loop, the speed of turning ideas into shipped work scales exponentially.我搭建让底层工程规模化的平台——把驱动构建、固件测试、崩溃分析这类缓慢、重复、依赖人工的系统级工作，抽象成贯穿整个技术栈的自动化工具。将 AI 融合进工作流中也是我的强项，依托于 AI，想法落地的效率呈指数级倍增。

About关于

A bit about me关于我

I'm Liu Tianyi — a platform and full-stack engineer based in Shanghai. I work on test infrastructure and system software: at Lenovo I own driver and platform tooling for the Windows core stack — Display, Graphics, and Power — behind Yoga and ThinkBook. Before that, at Quanta, I built the EFI/UEFI firmware test infrastructure for Apple MacBook, working directly with Apple's engineering team.我是刘天义——一名常驻上海的平台与全栈工程师。我专注于测试基础设施与系统软件：在联想，我负责 Windows 核心栈（Display、Graphics、Power）的驱动与平台工具，支撑 Yoga 与 ThinkBook；此前在广达，我为 Apple MacBook 搭建 EFI/UEFI 固件测试基础设施，直接与 Apple 工程团队协作。

What I actually do is turn messy, manual, low-level engineering into platforms — build/test/release pipelines, automated crash analysis, and knowledge that compounds. I'm comfortable from the driver and CI layers up to services and UI (a Digital Media Technology degree still shows up in how I sweat interfaces), and I reach for AI when it makes the analysis faster or the decision sharper. C#, C++, Python, Go; WinDbg to Docker.我真正做的，是把杂乱、重复、依赖人工的底层工程抽象成平台——构建/测试/发布流水线、自动化崩溃分析，以及会不断复利的知识沉淀。我能在驱动、CI 层与服务、UI 层之间自如协作（数字媒体技术的背景，至今体现在我对界面的较真上），并在能让分析更快、决策更准的地方引入 AI。C#、C++、Python、Go；从 WinDbg 到 Docker。
