Experience

Farming in The Future

A fully integrated MS Teams application for classrooms. 它使教师们能够展示技术如何迅速改变农业. 该平台是一个全栈物联网集成应用程序，每个学生在农场上都有一个带有几个传感器和一个摄像头的设备. 该应用程序允许学生和教师创建连接设备并实时可视化数据.

热路径是通过将数据流保存在Azure Cosmos DB的设备级别来实现的. 基于更新的设备集合触发Azure功能, and the live data was then sent to an API.

The API, built with Node.js and Express.js，然后使用WebSockets将数据转发给订阅的客户端. UI客户端是用React构建的，使用Mobx进行状态管理，使用ReCharts进行制图. UI客户端显示实时流传感器数据和流图像. 它还提供了对每个设备的历史数据的分析.

Applications for Data Scientist

我在许多项目中与数据科学家密切合作，将他们的AI/ML算法/引擎与应用程序工作流集成在一起. 数据科学家通常创建他们的AI/ML算法/引擎, whether it be a zero-shot classification algorithm, topic clustering, batch ranking algorithm, 或者根据组织的数据进行培训的定制聊天机器人. 我与他们密切合作，以了解算法本身以及所需的输入和输出. 我评估了处理时间，并从API和UI的角度设计了处理时间的架构. Once I had a full understanding of the AI/ML engines, 我围绕引擎创建了一个完整的平台(API和UI). api通常是用Python构建的，以便轻松集成AI/ML引擎, while the UIs were built in React. 我甚至通过为客户端集成OpenAI API，使用React构建了一个仅具有AI/ML功能的应用程序. 我对AI/ML有很好的概念理解，并且在这个领域的技术能力也在不断增长，这使得我很容易与数据科学家一起工作和合作.
