Technical FAQs

Why do you prefer Next.js over a standard React SPA?

While standard Single Page Applications (SPAs) are fine for internal tools, public-facing products require excellent SEO and fast initial load times. We use Next.js for its advanced Server-Side Rendering (SSR) and Static Site Generation (SSG), ensuring search engines can perfectly index your content while users get instant page loads.

Do you use utility frameworks like Tailwind CSS?

No. We build highly bespoke, scalable applications using pure vanilla CSS and standard CSS variables. This ensures your codebase remains completely independent of third-party utility dependencies, making it infinitely customizable, easier to debug, and drastically reducing HTML bloat.

How do you handle state management in complex applications?

We avoid over-engineering. For server state and caching, we rely on tools like React Query. For global client state, we prefer lightweight, highly performant solutions like Zustand, moving away from heavy Redux boilerplate unless specifically required by an existing enterprise architecture.
