About
Hello, World! I am Chánh Đại, a Software Developer & UI/UX Designer passionate about creating high-performance, user-centric software solutions with intuitive and engaging designs.
With over 5 years of experience in web development, I specialize in building high-quality web and mobile applications using Next.js, React, TypeScript, and modern front-end technologies.
Outside of my full-time work, I enjoy exploring new technologies and turning ideas into reality through personal projects.
One of my notable projects is ZaDark, a powerful extension that enhances the Zalo experience on PC and Web. Since its launch in 2022, ZaDark has surpassed 80,000 downloads on SourceForge and reached a peak of 10,000 active users on the Chrome Web Store.
