Do you write React applications in strict TypeScript?

Yes. All our production React and Next.js applications are written using strict TypeScript to eliminate runtime type errors and ensure long-term codebase maintainability.

How do you optimize React bundle sizes and performance?

We implement dynamic lazy imports, leverage Next.js Server Components, eliminate unused CSS via Tailwind, and utilize modern WebP image formats.
