Software Development Engineer II
Amazon
Aug 2017 - Apr 2020
2 yrs 9 mos
I belonged to the Mobile Shopping - App Experiences (AppX) team, where I worked on the navigation components of the Amazon shopping app. iOS (Objective C) -Created a sub-navigation bar that can be remotely configured via a backend service using JSON, thus enabling partner teams to design, deploy, and experiment without writing any native code. -Refactored the navigation bar and re-architected the view controller hierarchy of the iOS app to create a platform for partner teams to insert their custom sub-navigation bars. -Exposed the navigation bar's styling data via JavaScript, React Native, and native code APIs. React Native (JavaScript) -Implemented a React Native page that allows customers to toggle location permissions by feature such as Amazon Fresh or Treasure Truck. -Designed a technical plan to migrate both iOS and Android navigation bars to React Native, with an emphasis on app start latency, view rendering latency, and operational improvements. Backend (Java) -Migrated the Hamburger menu page to the new AppX personalization service, thus providing personalized "Shop by Department" and "Program & Features" content to customers. -Designed and executed the onboarding for the Me page to the new List Service API. As a result, customers can not only see their lists, but also see their wedding registries, baby registries, and more. Testing -Set up an automated UI test pipeline via AWS Device Farm and achieved 100% test pass rate. Operational Excellence & Team Communication -Wrote a self-service onboarding wiki page for partner teams who wish to introduce new marketplaces to the shopping app, thus minimizing the number of approvals from my team by over 50%. -Authored a new hire onboarding process that includes various topics such as partner team contacts, developer environment setup, and high-level architecture diagrams. -Set up metric dashboards for operational excellence meetings. -Configured auto-cut alarms with links for runbook documentation.
