    Questions

    Frequently asked.

    Do you build with Next.js or plain React?

    We default to Next.js for anything that needs SEO, server-side rendering, or a marketing site alongside the app -plain React (CRA/Vite) for internal tools and dashboards.

    Can you take over an existing React codebase?

    Yes — we regularly onboard onto existing repositories and run a short audit before proposing any changes.
