## About

I'm the founder and CEO at Briefer. Previously, I worked as a senior software engineer at Elastic and led software engineering teams at an early-stage startup in London. I used to maintain large OSS projects like Chai.js and Sinon.js and contributed to many others, including Jest. As an author, I wrote "Testing JavaScript Applications," published by Manning. I've also spoken in more than ten countries, and my content has been voluntarily translated into more than seven languages.
