I have a lot of experiences in developing single-page application using JavaScript. My expertise lies in developing web applications with React.js/Next.js and Vue.js/Nuxt.js. Also I have extensive knowledge in developing back-end APIs using Node.js and PHP. In addition, I always keep the clean code and logic of the infrastructure in the project. Through many years of working in some companies, I’ve learned many practical skills and experiences about how to cooperate with the other developers and how to improve the team spirit.
