Experience

Power Dialer for SellX

为SellX构建的自定义组件允许销售代表通过排队和自动拨号来拨打客户，而不是逐个单击每个客户. To do this, the client dials into a Twilio conference call, then individually dials the numbers it is supposed to, and auto hangs up if it detects a voicemail. 你可以通过设置加快或放慢这个过程，打开或关闭语音邮件检测功能. WebSocket is used to pass live information back and forth, so the dialer is in sync with what is going on as it is happening. 客户列表是通过汇总该特定日期的所有到期任务并将其组织到呼叫组中自动生成的. 总的来说，这是一个非常复杂的软件，是一个更大市场的一部分，但它提高了代表以正常速度两到三倍的速度拨打电话的能力.

Stadium Builder for Ticketing Platform

一个拥有美国职业棒球大联盟(nfl)赛季门票转售和管理网站的客户想要升级他们的网站，以便自己管理它. 它需要建立一个客户可以使用的自定义座位图，以便客户可以选择部分，并从各自的位置直接看到他们的座位.

I designed and built admin management and client-facing components in D3.js, allowing the company to build their own stadiums and save them. On the client-facing side, 它将渲染那个体育场，并允许他们选择一个区域来过滤基于该区域的结果.

It was an enjoyable project to build, test, 并根据地图搜索门票，而不是输入和填写随机过滤器.

Custom Messaging System for Privacy Client

该公司最初负责为CNN等出版公司测试和提供广告屏蔽信息. 打开AdBlock后，会显示“请关闭AdBlock”的提示信息. 客户很快发现这是一场艰苦的战斗，因为AdBlock不断更新以绕过这些信息. They decided to pivot to cookie and privacy management, but their messaging system was not built to handle that input.

I designed and built a custom messaging system that lets companies shape, color, label, 并更改设置，以创建任何他们想要的消息，并显示在他们的网站上给定特定的触发器. 我使用React作为构建器，使用Vanilla JS作为脚本来构建它，以确定要显示什么消息以及如何存储数据. Since it worked great, 我甚至可以采用以前系统中的AdBlock信息并将其放入我们的新信息系统和其他新信息系统中，如电子邮件订阅和隐私请求表单(CCPA). 在高峰期，自定义的白色标签信息每月被提取10亿次.
