Frontend Performance

The full Frontend Performance series — rebuilt as an interactive course. Watch each episode, then feel the problem and the fix in live demos: jank you can stop, a main thread you can unblock, and a 100,000-row list that scrolls like butter. From the critical rendering path to Core Web Vitals, monitoring, and shipping less JavaScript.

Frontend System Design

The full Frontend System Design series — rebuilt as an interactive course. Watch each episode, then go deeper with live demos, worked examples, and quizzes you can actually play with. Built around the RADIO framework and the real patterns you'll reach for on the job and in interviews.
