01 / ProfileAbout the engineer / 关于这名工程师

I build the whole product—not only the visible layer.

我构建完整的产品，而不只看得见的界面。

My work moves from interaction details and frontend architecture to APIs, agent runtimes, observability, and release paths. I care about how a product feels, how a system behaves, and whether the final result can be verified—not just demonstrated.

我的工作从交互细节和前端架构延伸到 API、Agent 运行时、可观测性与发布链路。我不仅关心产品看起来如何，也关心系统如何运行，以及最终结果能否被验证。

HOME MODE / ONLINE宅家模式 / 在线

Offline outside. Fully alive inside my worlds.

对户外离线，在自己的世界里满格在线。

I grew up in Leshan, Sichuan. Away from code, I am usually queuing for a match, cutting clips frame by frame, or disappearing into an anime universe. A proud homebody: quiet in the room, never short of worlds to explore.

我来自四川乐山。离开代码之后，我通常在等待一场对局、逐帧打磨剪辑，或干脆消失在某个动画世界里。一个理直气壮的大宅男：房间很安静，想去的世界却从来不少。

01Spawn point出生点

Leshan, Sichuan四川乐山

Mountains, rivers, spicy food—and the place that still feels most like home.

山水、辣味，也是直到现在最像“家”的坐标。

02Game queue游戏队列

APEX / Honor of KingsAPEX / 王者荣耀

Fast decisions, louder comms, one-more-game energy. Competitive when it counts.

快速决策、高能交流，以及永远再来一把的冲动。该认真时，胜负欲会准时上线。

03Creative mode创作模式

Video editing视频剪辑

I like finding rhythm between frames—timing a cut until the feeling lands exactly right.

喜欢在画面之间寻找节奏，把每个切点磨到情绪恰好落下。

04Core attribute核心属性

2D worlds > outdoors二次元世界 > 户外活动

Anime is not background noise. It is character, atmosphere, imagination—and a portal worth staying up for.

动漫不是背景音，而是角色、氛围和想象力，是值得熬夜进入的另一扇门。

05Default state默认状态

Indoor by choice主动选择宅家

Going out is optional. Working out is still buffering. Curiosity, however, stays permanently online.

出门属于可选项，锻炼仍在缓冲中；但好奇心始终保持在线。

03 / Side quests

Life outside the main quest.

主线之外，是我反复进入的日常支线。

Four recurring episodes. No productivity lesson hidden inside—just the things that make an ordinary night feel exactly right.

四个反复播放的日常篇章。这里没有隐藏的效率方法，只有让普通夜晚变得刚刚好的小事。

  1. EP.01

    A good story deserves a late night.

    好故事，值得熬夜。

    When a world, a character, or a soundtrack pulls me in, tomorrow can wait for one more episode.

    当一个世界、一名角色或一段配乐真正把我拉进去，明天可以先为下一集让路。

    WATCHING // 02:17
  2. EP.02

    One more game is a valid plan.

    再来一把，也是计划。

    Sometimes it is an APEX drop. Sometimes it is one more climb in Honor of Kings. Either way, ready means ready.

    有时是 APEX 再跳一次，有时是王者再上一颗星。只要队友还在，就没有真正的最后一把。

    QUEUEING // READY
  3. EP.03

    A good cut has its own rhythm.

    好的切点，自有节奏。

    Editing is the quiet pleasure of moving a moment by a few frames until picture, sound, and feeling finally agree.

    剪辑的乐趣，是把一个瞬间前后挪动几帧，直到画面、声音和情绪终于同时落下。

    TIMELINE // PLAYING
  4. EP.04

    Home is the main map.

    宅家，才是主地图。

    A screen, something to snack on, and nowhere I need to be. Not every memorable place has to be outside.

    一块屏幕、一点零食，以及没有非去不可的地方。值得记住的风景，并不都在门外。

    HOME MODE // 96%
04 / PracticeWhere I create leverage / 我创造价值的方式

One engineer. The whole path.

一名工程师，贯穿完整路径。

I move between the visible experience and the systems underneath it, keeping both craft and operational truth in frame.

我往返于用户可见的体验与背后的系统之间，让设计质感和运行事实始终处于同一视野。

01Interface to API从界面到 API

Product engineering产品工程

Turn fuzzy requirements into expressive interfaces, coherent state, and full-stack product paths that people can understand.

把模糊需求转化为有表达力的界面、连贯的状态，以及用户能够理解的全栈产品路径。

Clear experience · Solid foundation清晰体验 · 稳固基础
02Prompt to production从提示词到生产

AI & agent systemsAI 与 Agent 系统

Build task runtimes, tool workflows, evaluations, and human checkpoints around the way real work actually happens.

围绕真实工作方式构建任务运行时、工具工作流、评估机制和人工确认节点。

Useful intelligence · Visible control有效智能 · 可见控制
03Commit to accepted outcome从提交到验收结果

Reliable delivery可靠交付

Connect software, cloud infrastructure, observability, and release evidence so every handoff has a truthful definition of done.

连接软件、云基础设施、可观测性和发布证据，让每次交付都有真实可信的完成定义。

Lower risk · Faster feedback更低风险 · 更快反馈
05 / Capabilities

Across the stack, without losing the thread.

跨越技术栈，也不丢失产品主线。

I connect disciplines instead of treating them as isolated specialties. Each layer exists to make the whole product clearer, faster, and more reliable.

我不会把不同技术领域视为彼此孤立的专长。每一层都应服务于更清晰、更快速、更可靠的完整产品。
