A replacement audio video streaming application to improve performance and dramatically cut operational costs. 这项工作包括研究如何变聪明, 关于路线图上的核心功能和特性的长期决策. 整个流引擎都被替换了, and features were added, 例如可推荐的参与者，其中的操作被认证给推荐人, 主讲人模式，与会者可以通过音频和视频加入, waiting room functionality capable of holding thousands of participants until the session starts, 以及全新的用户界面和体验.
I was the top contributor to this project and a heavy influencer across the platform.

为一家最大的健康保险公司构建了一个SMS应用程序. The SMS application authenticated customers and fully integrated with existing chat systems. 功能包括语音XML文件，可以在通话时背诵消息, 许多钩子连接到api，将消息传递给数据分析, customer service storage, and other important divisions. 在构建时完全考虑了维护和可伸缩性.

模拟传真服务器，采用Linux、Hylafax、Asterisk、IAXModem和Node.Js用于在网络中发送和接收传真. 所有内容都是在VPN背后编写的，用于测试目的. It was used in an automation workflow to detect suspicious faxes and the application's overall functionality of a virtual faxing module.

一个将旅行计划组织到React用户界面中的应用程序. The back end was written in Node.js with Babel. Docker被用来隔离开发环境, and unit tests were written for front-end components and back-end functionality. 用户可以注册并登录到应用程序, where trips can be created, deleted, 或者用目的地详细信息进行修改, comments, and other information.

我构建了一个Angular应用程序来计算观察vs. expected stay ratios; made with Angular and Elixir with the Phoenix Framework. The most difficult challenge with this project was the lack of knowledge of Elixir before working through the tasks. The front-end application featured charts and data displays (tabular and detailed summary paragraphs) about the current month's stay ratios. The API featured a caching layer for non-PHI lookups and PDF generation for reports. Data processing and the application as a whole were implemented on an existing EMR database offset. 该项目部署到一个EC2实例上的AWS上.

A dashboard built in Angular to show energy consumption data from users with services with energy providers. The Angular front end used observables via RxJS to fetch and cache data from an API. The dashboard was used to display the differences between reusable energy consumption and non-renewable energy consumption. This involved charts and graphs which sampled large amounts of data from the API at different zoom levels.

The integration created organization charts and panels using the data to and from the ADP workforce API. There were a lot of abstractions to make the API requests and filter the proper data. The ADP API, in general, is quite verbose, 需要特定的属性以及请求的有效负载才能工作. 调查了其他api，包括休假管理和调度. In a previous project, ADP API用于将劳动力成员与数据库同步, which allowed the application to associate any of its data with any related data in ADP. 我负责整个整合.
