Build a polished multi-step form for a website. The form should guide users through questions, validate input clearly, preserve progress when appropriate, and submit reliable structured data to the backend. Accessibility and mobile usability are important because the form will be used by a broad audience. The successful freelancer will be expected to work independently, share progress at agreed checkpoints, and raise questions early when a requirement needs clarification. All submitted work should be original, well organized, and ready for practical use after reasonable review.
