Google CDN Migration

  • Migrated all frontend application static files to be hosted on Google's CDN

  • Implemented this process across 3 applications: CPR, BASS, StoreFinder
  • My implementation was then copied by all other frontend applications where I provided guidance as needed
  • See screenshots

HeaderFooter Independence

  • The CSS and JS for HeaderFooter was bundled inside of every application
  • The goal of this initiative was to decouple application releases from updates to HeaderFooter
  • To do this, I had to remove HeaderFooter dependencies from each application and then create separate external bundles for the CSS and JS
  • These external bundles were then hosted on the Google CDN, and loaded prior to the application bundles
  • After testing this implementation in the StoreFinder application, my approach was then copied by all of the other frontend application teams
  • See screenshots

Localization Standardization

  • Normalized the frontend component apis provided to other teams for them to access a users localization information
  • Over time, too much custom code had been written to access user localization information, eventually small differences in this code began creating severe bugs where localization information became corrupted or could changed randomly
  • The bugs resulting from this often caused an order to be sent the wrong store, costing millions in losses every year and inflicting brand damage
  • For this feature, I had to migrate all applications and libraries dependent on localization information to use this new component
  • I made the changes to every project myself, and it included over 20 applications and libraries
  • In addition to the frontend changes, I also had to remove all localization logic from the backend of every application, and refactor them to localize the user on the frontend
