Create Comprehensive Product Design Specification

I have already written a detailed PRD for my new startup and now I need it transformed into a rock-solid Product Design Specification. The finished PDS must cover the full experience for Web, Mobile and Desktop, turning every requirement I have captured into clear interaction flows, annotated wireframes, UI states and visual references. Because I am starting from a blank slate on brand and style, you will have complete freedom to propose a visual language, colour system, typography and component library that feels fresh yet scalable. At the same time, I expect the document to include the same depth of legal content that exists in the PRD—proper warnings, age-gate language where required, disclaimers, copy for opt-in consent, GDPR considerations and any other statutory notices a professional product document should carry. Nothing should be left to chance. Core features that must be mapped out in detail include user authentication, payment integration and real-time notifications, plus every other workflow called out in the PRD. Think through edge cases, error states, empty screens and localisation placeholders so development can start immediately after sign-off. Deliverables • A single, version-controlled PDS (PDF or Figma file with export) that covers: objectives, personas, journey maps, sitemap, UI wireframes, high-fidelity mock-ups, component specs, accessibility notes (WCAG 2.1 AA) and a dedicated section for all legal cautions/warnings. • Source design file (Figma/Sketch/Adobe XD) with organised layers and reusable components. • A short hand-over video or call walking me through the document. Acceptance criteria • Every requirement from the PRD traceable to at least one PDS section. • All screens provided for Web, Mobile and Desktop breakpoints. • Legal section reviewed against the PRD checklist with no omissions. If you have strong UI/UX chops, a methodical product mindset and can write clearly in English, I’m ready to collaborate right away.
