Noveria's ambition is simple: build one of the strongest and most trusted brands in the Spanish energy renovation sector. This website will be the public face of our company. It must combine elegance, modern design, excellent performance and a premium user experience. We are not looking for a standard template website.

A complete specification document is already available. It describes: • website architecture; • page structure; • branding direction; • user experience; • animations; • technical requirements; • expected deliverables. We are looking for someone who: • has experience creating premium corporate websites; • understands modern UI/UX principles; • writes clean, scalable and maintainable code; • pays attention to performance, SEO and responsiveness; • communicates clearly in English; • can work independently or with a trusted UI/UX designer if needed. We are open to your technical recommendation. If you believe Next.js, Webflow or another modern technology is the best solution, please explain why in your proposal. Please include: 1. Three premium websites you have built. 2. Your recommended technology stack. 3. Whether you work alone or with a designer. 4. Your estimated timeline. 5. Your fixed-price quotation. 6.
