### Software Development Engineer II @ Amazon
Jan 2017 – Jan 2020 | San Francisco Bay Area
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.

### Retail Engineering Intern @ Apple
Jan 2016 – Jan 2016 | Sunnyvale, CA

Uses Jetty embedded Java Servlet, Handlebars.js, HTML/CSS/JS, Java, Jackson, and Maven.

Built a dashboard webapp that SSHs onto remote machines, pulls environment/build data, and displays it in tables with a RESTful API. Uses Jersey, Apache Tomcat, HTML/CSS/JS, Ajax, jQuery, and Java.
