Scaling up the IoT Hub

为全球分布式系统扩展物联网中心，以更好地服务于不断增加的服务器负载, improve stability, and support upcoming feature development.

我将中心的职责分解为特定的用例，并相应地重新组织了代码. Certain patterns emerged, 提供了一个很好的机会来创建一个轻量级框架，它具有类似插件的用例，并从集线器中心提取大部分功能. 这消除了主要的瓶颈，允许处理更高的负载. The framework streamlined the control flow and reduced code duplication, allowing the use-case code to focus solely on specific business logic.

I relied heavily on an API test suite, complementing it where it was lacking, and did all the heavy modifications in the code incrementally, while continuously keeping it functioning. The modifications passed QA and went to production without a single flaw.

LogMeIn Rescue

基于网络的远程支持解决方案将成为GoToAssist和Rescue的下一个版本.

我作为开发者加入的时候，这个项目还处于实验阶段, 我跟随它成长为一个分布在全球的大型服务. As a full-stack developer, 我直接开发了许多后端和web前端的功能.

As the project and the team grew, so did my responsibilities. 我将注意力从开发功能转移到让20多名工程师组成的团队更快更好地开发. This involved system and software architectural work, building a CI/CD pipeline, API testing, process development, product usage analysis, and mentoring junior colleagues.

我的开发任务包括项目中最复杂的问题，以及需要对后端和前端进行基本扩展的特性. Most often, 我是在新功能通过市场验证后稳定其早期实现的人.

Automated Back-end API Test Suite

一个测试后端域的框架，使用与前端相同的WebSocket通道.

Over the years, the framework matured significantly as the domain and the test suite grew, 使得用5-10行代码编写(否则会很复杂)测试用例变得非常容易. The tests ran in VSTest with no outer dependencies, using in-memory databases and mock services, making them very fast. 这些API测试使得在集成测试级别上测试驱动特性开发并安全地对代码进行巨大更改成为可能.
