How to Structure a Frontend System Design (Interviews & Architecture Reviews)

👉 Frontend System Design Essentials — Course: https://icodeit.thinkific.com/courses/frontend-system-design-essentials 👉 Frontend System Design Essentials — Book: https://leanpub.com/frontend-system-design-essentials/ Preparing for a senior frontend system design interview is not only about knowing React, APIs, caching, and performance. You also need a clear structure so the interviewer can follow your thinking. Last year I shared CCDAO — a simple framework for frontend system design interviews. After using it on typeahead, feeds, notifications, chat, whiteboards, and board apps, two areas needed to be sharper: data modeling and API design. In this video I walk through a refined CCDAO for 2026. It is still the same five-step path, but with more precise names and senior-level depth on state, synchronization, and production reliability. 📘 MY BOOKS & COURSES 👉 Frontend System Design Essentials (Course): https://icodeit.thinkific.com/courses/frontend-system-design-essentials 👉 Frontend System Design Essentials (Book): https://leanpub.com/frontend-system-design-essentials/ 👉 React Anti-Patterns (Amazon): https://www.amazon.com/dp/1805123971 👉 More Tutorials on Books: https://leanpub.com/u/juntao 📩 STAY CONNECTED 🧠 Newsletter (system design & clean code): https://juntao.substack.com 🌐 Website & Blog: https://icodeit.com.au 🐦 Twitter / X: http://twitter.com/JuntaoQiu 📺 YouTube (subscribe): https://www.youtube.com/@icodeit.juntao #frontend #systemdesign #frontendinterview #systemdesigninterview #react #webdevelopment #seniordeveloper
