How does it help with Core Web Vitals?

The skill provides actionable guidance on improving LCP, FID, and CLS through image optimization, font subsetting, code splitting, and efficient rendering patterns.

Does it provide infrastructure-level advice?

Absolutely. It covers AWS-specific optimizations such as Lambda memory allocation, provisioned concurrency, and CloudFront caching strategies.

Can it help with database bottlenecks?

Yes, it includes specialized patterns for MongoDB, including index management, projection optimization, and solving the N+1 query problem.

Which frameworks does this skill support?

It specifically focuses on React, Next.js, and NestJS, but the core principles can be applied to many modern JavaScript-based web applications.
