  Mini Program Developer Tools - Compilation (Node.js, Esbuild, Pkg) 2022.4 - 2023.10 - Core Developer

  The compilation of mini programs is a critical aspect of the simulation, debugging, localization, and preview release process in mini program development. I participated in designing the new compilation architecture and independently implemented complex compilation processes for entries and CSS.
  • Addressed issues with compilation performance and stability; improved performance by introducing concurrency and merging multiple AST parses, resulting in an 85% increase in full compilation performance and a 70% increase in incremental compilation speed.
  • Optimized code; developed more granular features of the PostCSS plugin, optimizing the CSS processing flow.
  • Resolved packaging performance issues; utilized Esbuild and multi-threaded Terser to optimize mini program packaging performance. Summarized best practices for multi-thread compression, resulting in a 77% increase in compression performance.

  Low-code SDK for ERNIE Bot (Rollup, San, Less) 2023.10 - present - Leader

  A low-code framework for developers of the ERNIE Bot. Developers can generate plugin UIs through JSON config. Currently integrated on multiple large model platforms at Baidu; as the project leader, I finalized the architecture design and constructed the project from the ground up.
  • Supported developers to create custom plugin UIs by coding JSON, running on multiple AI models.
  • Supported UI components such as markdown, dynamic charts, and biomolecules.
  • Integrated with CI/CD pipeline and testing.

  Mini Program Runtime Framework 2020.4 - 2022.4 - Core Developer

  • Improved performance by preloading resources and optimization of components.
  • Enhanced the error monitoring system for the framework.
