Master how to build scalable, high-performance frontend systems. From browser internals to architecture patterns.
What You'll Learn
Each week builds on the last — from how the browser works all the way to designing production-grade systems in interviews.
Rendering pipeline, event loop, reflow vs repaint, and how the browser actually paints pixels.
Virtual DOM, memoization, state colocation, virtualization — diagnose and fix slow renders.
HTTP lifecycle, caching headers, CDNs, and storage trade-offs for real-world apps.
XSS, CSRF, auth token storage, and secure-by-default component design.
Smart vs dumb components, feature-based folders, and scalable state management.
Design infinite scroll, chat UI, dashboards — and practice explaining your decisions.
