<h2>Work and Project</h2>

<h3>1. Ant Group, December 2018 - Present, Shanghai</h3>

<h5>Stock Business, June 2023 - Present</h5>

<p>随着养老金业务的稳定，年中回归了股票业务。</p>

<h5>Pension Business, August 2022 - June 2023</h5>

<p>22年底个人养老金政策颁布，政策落地前夕，我加入了养老金团队承担保障业务开闸对外的工作。</p>

<p>养老金业务很早就在为个养开闸做准备，但是系统的稳定性并不可靠。我加入团队后 review
了关键链路的方案和实现，修正了一些问题。比如，调整了切流开关设计不合理的问题，使得个养阵地能够同时支持开闸前后的状态，持续迭代。完全承接了大促活动项目，与产品对焦玩法链路、逐行 review
大促活动的代码，并在对外前发布上线。基于以往的经验，切流将是开闸对外非常重要的一项功能，因此提前做好了技术准备，最终支持了项目组、蚂蚁集团、阿里巴巴集团、城市维度、百分比粒度的放量对外。</p>

<h5>Securities Wealth Management Business, January 2022 - August 2022</h5>

<p>在此期间，我虚线带2名同学跟进券商理财业务。除了写代码，日常还需要进行需求评估、项目分工、技术规划等工作。比如，协助团队同学进行市场页接口性能的分析与优化，解决了系统发布时服务器重启引发的接口耗时增加的问题。</p>

<h5>Stock, Pension, Investment Research, Community Business, April 2020 - December 2021</h5>

<p>20年4月新入职了一位同学，组织任命其为 Team
Lead，并开始组建新团队。团队初期定位为终端基础，要求能够云动支持上一级大团队的业务。我作为核心开发在这个阶段经历了频繁的业务变动，在股票、养老金、投研、社区等多个项目中独当一面，证明了团队的战斗力。最终团队得到组织认可，得以负责完整的股票业务，并剥离了其它规模较小的业务。
</p>

<p>
在接手养老金业务后，刚好面临财富+保险融合的大改版需求。我作为负责人完成了从需求分析到开发上线的大部分工作，最终顺利切流对外。在紧张的工程开发期间，我还对发现的一些体验问题进行了优化，如首页加载闪动的问题。由于首页头部卡片逻辑复杂，架构设计上将首页的数据处理分成了两个
model (页面 model 和 头部卡片
model)。分析发现由于头部卡片处理耗时长，而页面框架整体反而结构简单，能够快速处理。若页面数据已处理完成并渲染，然后头部卡片才处理完成，此时头部卡片渲染出来，便会造成闪动的问题。解决方案是在两个 model
之间加上了时序控制，页面 model 只有等到头部卡片 model 的数据处理完成，才允许提交数据。最后完美的解决了该问题。</p>

<p>在投研业务中，前端需要开发一个内部 B 端应用，用于展示金融工程同学生产的数据，同时还需要维护一个对外的 B 端应用，功能是内部应用的子集。应用采用 BFF (Backend For Frontend) 架构，一组前端
+ nodejs 应用提供对内服务、另一组前端 + nodejs 应用提供对外服务。前端使用 npm 包来共享页面样式，nodejs
层使用插件来共享接口实现。我从0到1完成了整个应用系统的搭建，并带领2个外包同学进行业务迭代，在此模式下支撑了业务的发展。</p>

<p>在股票业务中，存在如下两个问题，一是如股票首页这种 H5 页面，启动速度慢体验差，二是使用原生 iOS/Android
技术开发时，人力资源耗费大、业务迭代效率低。基于支付宝自研的高性能动态化引擎，进行了股票研发模式的升级改造。我负责打通服务端的数据链路，对接管理后台并在 nodejs
层封装成业务可用的接口，与客户端同学联调配合，完成改造上线。股票首页完成改造升级后，平均启动时长从 2000ms 缩短到了 700ms。股票详情页接入该链路后，研发效能提升50%。</p>

<p>
用户对股票详情页不同标的的访问情况，能够侧面体现出市场当前的热度。前端会上报用户的访问数据并记录到数据仓库，因此也是离数据源头最近的角色。在此背景下，我在业余时间学习了洗数据的流程，并制作了一份股票详情页分个股、指数、板块各类型的
top UV 的报表。口口相传，目前已有10+左右不同业务线的运营同学申请了该报表权限，起到了辅助业务决策的作用。

<h5>High-net-worth Wealth Management Business, December 2018 - March 2020</h5>

<ul>
<li>When I joined the team, the business development was in progress and not yet launched externally.

It was necessary to quickly complete the development of various functional modules and complete end-to-end
integration to ensure business expansion at any time.

The front-end team was consisted of 3 people. In the early stages, I was responsible for developing a
mini-program for dual recording (audio and video), and later I was responsible for the entire front-end
project.

Ultimately, the business was successfully launched to the outside world in the middle of 2019.
</li>

<li>Under the 2018 new regulations for asset management of China, it should make audio and video
recordings before purchasing trust products.

I developed a dual recording mini-program for this purpose.

The dual recording mini-program relied on many basic capabilities provided by other teams, such as TTS audio
synthesis, audio playback, audio recording, video recording, and mini-program framework.

Integrating these basic capabilities to build the business application required resolving numerous
compatibility issues.

For example, on Android devices, the duration of TTS audio was always shorter than the actual audio
duration, resulting in abnormal progress bar display for audio playback.

After failing to find a solution from the multimedia team, I collected data points and conducted visual
analysis .

I discovered a fixed multiple relationship (always equal to 1/2 of the actual value) between the TTS audio
duration
callback value and the actual value.

Based on this finding, I corrected the problem and improved the user experience.

After multiple rounds of optimization, the pass rate for dual recording tests increased from
being almost unusable initially to 70%, effectively supporting the expansion of trust business.
