๐ŸŽค App Performance: Tools and Optimizations ๐ŸŽค
Andrew Goodale (

Diagnosing and fixing performance problems in React Native apps can be a complicated endeavor. The documentation for many tools is sparse. Knowing where to look can be a challenge. This talk will give you an overview into the techniques my team used to analyze and fix performance issues in our large application. Youโ€™ll learn about the Stall Debugger, the JavaScript runtime, and ways to instrument your code to better find performance bottlenecks.


Andrew is a senior mobile engineer at Upserve, Inc. in Providence. He's been doing React Native for the past two years. Before that, he was building web applications in React, and iOS applications in Objective-C. Andres has been writing software since 1995 for companies large and small.


๐ŸŽค Using Go in React Native ๐ŸŽค
Dan Wiese (

Using React Native to build a mobile app offers many well known benefits, but carries drawbacks as well. One of these drawbacks is performance, sometimes necessitating substantial code be written natively. This can be a challenge for new developers or small teams with limited native experience. When supporting multiple platforms, this means implementing the same functionality in multiple languages which can slow down development and increase cost. One solution is to write this code in Go, which provides several additional benefits as well. In this talk, I'll give an overview how performant modules can be written in Go and used in a React Native app, and share some of the benefits such an approach offers.


Dan is the CTO at Humon, leading their technical team in building the next generation of wearable sensors for athletes. An aerospace engineer by training, he was first introduced to React Native about a year and a half ago.

When you walk in you will go through the glass doors to Lingo (bar/cafรฉ) and turn immediately to the left where you can either take the stairs or elevator up to the 2nd floor.

For parking there is street parking, and we are a short walk from the Museum of Science and Cambridge Galleria Mall.
