In April 2015, I had the opportunity to build an AngularJS application to showcase my coding skills. It was fun building this little app that did not have a backend whatsoever. Everything was client-side, even the data storage via local storage in the browser. Check out the demo here at http://notemanager.bryanlor.com.
