Emily Nakashima is a full-stack JS developer who loves design, web performance, and metrics. She currently works at honeycomb.io as an engineer and has experience in full stack development, browser JavaScript, and browser monitoring. Emily has a genuine concern for user experience and will share her experiences in monitoring events that potentially indicate frustration with the UI in her talk at Influx/Days 2017. She will discuss strange cases she's seen in browsers, such as overseas proxy sites and rogue browser extensions, and provide advice on how to cut the noise and focus on minimum viable instrumentation to have visibility into user experience metrics.
