  • Created from scratch a VIP income system by conducting the end-user interview before working on the design independently in the absence of a designer. The system led to 60% fewer mistakes made in the daily operations of the VIP team.
  • Optimized the performance of a gift management system with large lists. Before the optimization, it was sluggish and the drag-and-drop far from satisfactory; however by reducing the number of elements when rendering it can finally deliver a silky 60FPS experience.
  • Created an internal CLI to facilitate deployment process. It allows developers working on different features and deploy them independently on different URLs while still sharing the same backend server. It greatly facilitates the deployment process for everyone and makes it easier for them to demonstrate the new features to the end users independently.
  • Led the team on exploring best practices and drawing up schema conventions for GraphQL-based developments.
  • Built a refined testing environment for our team by integrating Circle CI with GitHub, and compiled documents on the unit test guide.
  • Upgraded React to v16 without breaking anything with the help of e2e tests, codemod and a thorough validation plan.
