ServerMania's SSR Website
http://www.servermania.com主要目标是提供一个大约有300页的网站，可以很容易地更新新内容. A significant amount of pages should be designed to be data-driven friendly.
I was a technical lead on this project, and I'd chosen Nuxt.js as a framework because it combines benefits from Vue.js and the SSR approach, which makes an app SEO-friendly. Starting from scratch, I designed the architecture and CI/CD, implemented crucial low-level parts, and managed other developers to complete the project.
我们提供了一个极快的网站，具有动态内容支持和易于维护和扩展的代码库.

ServerMania's Lockstep
http://lockstep.servermania.comThe goal was to provide a transparent, supervisable, 以及在公司计费平台和第三方营销服务(如activeccampaign)之间同步数据的可靠方法, Wicked Reports, and Zoho Analytics.
As a senior developer, 我负责实现最有价值和最复杂的架构部分. I also spent some time mentoring other team members, 因此，我们可以实现项目目标，并通过实际案例的学习来提高他们的技能.
We released an app with a zero-downtime policy, fast syncs, and complete logs. At this point, 市场部总是确信他们的报告使用了100%有效的数据，没有任何遗漏.

http://order.servermania.com主要目标是为公司的客户提供一种方便的方式来自动订购服务器的软件包.
The project had complex feature and performance requirements. As a lead full-stack developer, I've implemented the basic architecture and required features using Vue, Go, and PostgreSQL. Those features included:

Awesome Notifications
http://github.com/f3oall/awesome-notificationsThe main goal was to provide a tool to easily create toast notifications. 它应该是轻量级的，易于使用，支持异步流，并提供数据驱动的API.
我决定让它开源，这样我就可以帮助社区解决类似的问题. I developed it from scratch using Vanilla JS and CSS without any dependencies.
生成的库大小为4KB，使用起来很方便，并且有详细的文档. In no time, it became popular and got hundreds of thankful users.

ServerMania's Blog
http://blog.servermania.comThe goal was to create a blog that content writers could easily update.
As a leading developer, 我选择WordPress作为平台是因为它满足需求并且可以快速实现. 然而，出于性能和定制的原因，我不得不开发一个自定义WordPress主题.
Unlike most other companies, 我们已经成功地将Git和GitLab CI/CD集成到WordPress开发流程中, 让我们以一种高度监督和可靠的方式使用WordPress.

ServerMania's Knowledge Base
http://www.servermania.com/kb目标是为公司的客户创建一个自我支持中心，内容作者可以轻松更新.
This project had a lot in common with the company's blog, so, as a leading developer, I decided to use WordPress again. However, we also needed a custom WordPress theme, in this case, for performance and customization reasons. Still, since we already had one for the blog, I just adapted it, reusing most of the existing codebase.
我们得到了一个功能齐全的自助支持中心，使用的代码库与我们之前的WordPress项目几乎相同. 这有助于减少维持这两个项目所需的资源数量, which can persist up-to-date without noticeable efforts from the development team.

ServerMania's Surge
该项目的目标是创建一个包含账单处理的复杂应用程序, a support center, a dedicated servers' control panel, marketing reports, and a batch of other tools.
This was the most complicated and long project I've ever worked on. We had a small development team, and as a benefit of such a small team size, I could participate in developing each feature using a non-trivial stack—Go, MongoDB, GraphQL, and Vue.
Despite all difficulties, we released this app in time, 这是公司历史上的一个转折点，因为这个应用程序极大地增强了业务流程，提高了ServerMania在市场上的竞争力.

YQueue SSR Website
http://yqueue.co主要公司的网站是在SSR的支持下建立的，最初是在next的支持下.js should have been used as an engine. Still, after I was hired, 我做了需求分析，并基于我对不同SSR引擎(包括next)的丰富经验.js), I advised using Astro.js instead as a more performant solution.
该项目的主要挑战是复杂的动画和每个地区不同内容的渲染. 我成功地应对了这些挑战，不仅满足了每一个要求，而且以最好的表现完成了任务.
