As a full-stack developer, my primary focus is on the programming languages PHP, JavaScript, Vue.js, and Flutter. In web development, I have expertise in using PHP as a back-end programming language and JavaScript along with Vue.js for front-end development. I can implement business logic and handle data management using PHP, as well as create responsive and interactive user interfaces using JavaScript and Vue.js. Furthermore, I have experience in developing mobile applications using Flutter. Within the Flutter environment, I can use the Dart programming language to build cross-platform mobile applications with appealing user interfaces and high performance. As a full-stack developer, I possess the ability to integrate front-end and back-end components in web application development and develop mobile applications that connect to the back-end through APIs. I can design and develop applications end-to-end, starting from user interface creation to database management and business logic implementation. With my proficiency in PHP, JavaScript, Vue.js, and Flutter, I am well-equipped to tackle various tasks and challenges as a full-stack developer, both in web development and mobile application development.
