Please tell us about your experience: what did you do, what did you write?

In my front-end development experience, I have been involved in creating and maintaining web applications using React and Vue.js. I wrote user interface components, integrated REST API and WebSocket for dynamic data updates. I worked with TypeScript to improve code reliability, and also used Redux and Vuex for state management. In my projects, I paid attention to responsive design and performance optimization, including lazy loading and code splitting. I also wrote unit and integration tests with Jest and Cypress.
