I am a front-end developer with about 4 years of experience. I started with HTML/CSS and JavaScript, gradually delving into React and modern build tools like Webpack and Vite. I have participated in several major projects, focusing on performance optimization and UX improvement. One of my achievements is implementing a lazy loading system for components, which reduced the first render time by 30%. I also actively use TypeScript to improve code reliability and reduce bugs. In my free time, I study new frameworks and keep up with trends in web development.
