# Hadley Crowl > Software Engineer Location: Austin, Texas, United States Profile: https://flows.cv/hadleycrowl Hi, I'm a software engineer with five years of experience building applications using the latest web technologies, including Typescript, React, React Native, and Electron. At Evernote, I worked on a growth experiments team where I built and A/B tested features to improve user engagement and retention across mobile, desktop, and web apps. When I'm not working I'm probably working on a mechanical keyboard project, 3d printing something, or bouldering. ## Work Experience ### Senior Software Engineer @ Reflex Jan 2023 – Present | Austin, Texas, United States ### Senior Software Engineer - Growth Experiments @ Evernote Jan 2022 – Jan 2023 | Austin, Texas, United States At Evernote I worked on a growth experiments team where I built and A/B tested features to improve user engagement and retention across mobile, desktop, and web apps. - Rebuilt the Tutorial Center for the Evernote mobile app, which helps new users get familiar with the most important features of Evernote.
