Technologies: React, React Native, Node.js, TypeScript, JavaScript, Babel, Webpack, Vite, Jest, Android, IOS, Figma • Designed and shipped end-to-end product features across web and mobile for a core food-delivery module serving millionsof users. Collaborating closely with product managers, translated business requirements into scalable technical solutions, and owned development from UI to API integration. • Built a cross-platform UI library with 41 base/domain components, encapsulating a unified glue layer for web and mobile. Implemented Jest-based unit tests to ensure component correctness; dynamic PC/Mobile loading reduced shared code and saved 2.9 developer-days per feature. • Designed a Babel-based AST analysis tool to analyze component dependencies and integrates with Webpack and Vite builds, enforcing architectural constraints through CI/CD and reducing code review time by 30%. • Integrated an AI-powered recommendation feature into the component library by connecting to LLM-style APIs, enabling intelligent suggestions of suitable UI components based on usage context and developer needs.

Technologies: React, React Native, Node.js, TypeScript, JavaScript, Monorepo, Micro-frontend, Figma • Collaborated with UI/UX designers and multiple engineering teams; contributed 60,000+ lines of code in 5 months to core modules of the Live-Streaming Workbench and micro-frontend projects in a monorepo-based One-stop Operations Platform; leveraging Redux and React Hooks for scalable state management, improving system scalability and boosting product penetration to 90%. • Proactively investigated performance issues caused by excessive DOM reflow/repaint leading to lag; introduced optimizations such as react-virtualized and custom routing hooks, cutting first-screen render by 200ms, and eliminating scroll lag on large lists. • Developed shared UI components adopted by 300+ internal usages, improving cross-team consistency and reducing production on-call issues by 60%. • Refactored state management to Recoil, and proactively shared the technical approach and migration guidelines with the team, improving code clarity and cross-module reuse.

Technologies: Spring Boot, Java, Vue.js, Node.js, Ruby on Rails, TypeScript, JavaScript, MySQL, PostgreSQL, Maven • Worked in a cross-functional Agile team with researchers and backend engineers to build a high-throughput bioinformatics web platform using Scrum practices (sprint planning, stand-ups, reviews). • Collaborated on frontend feature development using Vue + TypeScript, integrating Element UI and implementing token-based authentication with Axios interceptors. • Delivered back-end features with Spring Boot + MySQL; Contributed to system architecture design using GraphQL. • Improved maintainability by refactoring repetitive code and extracting shared business components.
