About
Hello, World! I am Chánh Đại — a Design Engineer passionate about creating high-performance, user-centric software solutions with intuitive and engaging designs.
With 5+ years of experience, I specialize in building high-quality web and mobile applications using Next.js, React, TypeScript, and modern front-end technologies. Beyond work, I love exploring new technologies and turning ideas into reality through personal projects.
One of my key projects, ZaDark, enhances the Zalo experience on PC and Web, surpassing 80,000 downloads on SourceForge and 15,000 active users on the Chrome Web Store since 2022.
I'm also the creator of React Wheel Picker — iOS-like wheel picker for React with smooth inertia scrolling and infinite loop support. It has earned 221 stars on GitHub and was selected for Vercel Open Source Program summer 2025 cohort, receiving $3,600 in Vercel platform credits, an OSS Starter Pack, and priority community support to fuel its ongoing development.
