Nadia Makarevich is a software engineer and React educator (formerly Atlassian) focused on the deeper performance side of React applications — particularly the rendering-and-reconciliation patterns that determine whether a React app stays smooth as it grows. She is one of the more cited independent voices on React performance specifically.
Her CourseFlix listing carries Web Performance Fundamentals — a structured treatment of the modern web-performance discipline: the Core Web Vitals, rendering performance, bundle-size patterns, the React-specific performance considerations, and the engineering decisions that separate fast applications from slow ones.
Material is paid and aimed at intermediate-and-up React developers ready to take performance as a deliberate engineering concern. For broader content, see CourseFlix's React.js and Web Performance category pages.
