Juntao Qiu

Hello! I'm Juntao — an experienced software developer specializing in clean architecture, performance, and frontend system design. Over the years, I've repeatedly seen how tangled states, unsuccessful data flows, and short-sighted rendering decisions can lead projects to failure, and my goal is to help developers avoid these pitfalls. In my books Test-Driven Development with React (2021), Maintainable React (2022), and React Anti-Patterns (2024), as well as on my YouTube channel I Code It, I share practical approaches to refactoring, testing, and building scalable frontend applications. My main goal is to teach you to think like a system architect, rather than just implementing features, and to help you grow into a confident senior-level engineer.
