React Homepage Speed Optimization

My React-based homepage is noticeably lagging and I want it running lightning-fast. The biggest pain points are large images and video assets, a handful of third-party scripts/plugins, and the way entire sections are being rendered. Even the basic forms on the page feel sluggish, so field validation and first input delay need tightening as well.

Here’s what I need from you:
• A quick but thorough performance audit (Core Web Vitals, network waterfall, bundle analysis).
• Concrete fixes—lazy-loading or next-gen formats for media, code-splitting where it matters, script deferral/cleanup, and streamlined form logic without breaking existing functionality.
• A short report that shows the before/after metrics so I can track the improvement and replicate your approach on future builds.

The site is plain React (no Next.js), hosted on a standard VPS with Nginx, and deployed via Git. If you’ve tamed heavy React front pages before and can hand back a faster, cleaner bundle, let’s get started.
