optimize

Fix slow loading speed and rendering jank by diagnosing Core Web Vitals and bundle sizes, then applying an optimization framework for loading, rendering, and animations with before-and-after validation.

The best way to reduce heavy bundle size for UI optimization is to measure current load times and bundle metrics, identify bottlenecks, and apply targeted network and bundle size strategies to deliver faster, smoother user experiences.

Diagnose Core Web Vitals for slow route transitions by measuring load times and bundle sizes across initial page loads and intensive interactions to identify bottlenecks and guide practical fixes.

UI performance optimization works across both web and mobile apps, addressing slow loads, jank, and heavy bundles in scenarios like initial page load, route transitions, and intensive interactions.

Web apps experience jank after initial page load due to unoptimized rendering, animations, or heavy bundles during route transitions and intensive interactions, requiring measurement and targeted fixes to resolve.
