About Me

๐Ÿ‘‹ Hi, I’m Jin Yu

Iโ€™m a Full-Stack Developer and System Designer, passionate about building high-performance, scalable, and deeply modular web applications.

My work sits at the intersection of frontend architecture, backend logic, and AI-driven experiences โ€” where design, code, and performance meet.

โš™๏ธ What I Do Best

๐Ÿง  Frontend Engineering

  • Deep understanding of Vue and React internals โ€” Iโ€™ve even built my own decorator-based Web Component framework, decoco, inspired by their core rendering principles.
  • Designed a dynamic multi-page form system with a five-layer architecture balancing maintainability, predictability, and isolation.
  • Created six-layer performance optimization model, improving CPU-intensive operations via hidden-class optimization.

๐Ÿš€ Performance Optimization

  • Deep dive into V8 engine behavior and Blink/Gecko rendering pipelines.
  • Solved memory leaks in Vue Devtools and optimized virtual scrolling for unpredictable mobile heights.
  • Capable of pushing PageSpeed scores above 90 even for video-heavy WordPress landing pages.

๐Ÿ”— Full-Stack Capabilities

  • Node.js as the core, Python as the supportive backend โ€” balancing rapid prototyping with system stability.
  • Experienced in building SaaS and AI-powered tools, including an AI resume platform: aijianli.top
  • Skilled in integrating third-party services, automating workflows, and architecting scalable systems.

๐Ÿงฉ System & Component Design

  • Strong focus on reusable architectures โ€” modular configuration, strategy and factory patterns, and clear type constraints via TypeScript.
  • My philosophy: compose, donโ€™t inherit โ€” building flexible systems without losing clarity or control.
