Polish SaaS Demo for Prospecting

We have a working demo of our B2B SaaS platform live on Vercel. It's about 80% of the way there visually, but there are rough edges — some screens feel unfinished, some demo data looks sparse or inconsistent, some buttons don't go anywhere, and the overall polish isn't where it needs to be to put in front of paying prospects. We're hiring someone to take this demo across the finish line so it looks and feels like a complete product in a sales demo. This is not a full product build. We're not wiring up real integrations, real AI, real auth, or a production backend. Fake/seed data is fine. The goal is purely: "when a prospect clicks around for 15 minutes, every screen looks finished and nothing visibly breaks." What success looks like - Every screen a prospect might click into looks fully populated with realistic demo data - No dead buttons, no "coming soon" placeholders, no obvious half-built sections - Visual consistency across the app (spacing, typography, color usage, component states) - Hover states, empty states, loading states, and basic interactions all feel polished - Core demo flows — the ones we'll click through on a sales call — work smoothly end-to-end against seeded data - Mobile/responsive isn't required unless something is visibly broken on a laptop What we'll give you - Full access to the repo (Next.js + TypeScript + Tailwind, Vercel-deployed) after an intro call - A walkthrough of the current demo and the specific flows we want prospect-ready - A punch list of ~15–25 items we've already noticed, plus freedom to surface anything else that looks off Who we're looking for - Strong frontend chops in Next.js (App Router) + TypeScript + Tailwind - Taste — you can look at a dashboard and tell what feels unfinished vs. finished - Comfortable working against seeded/mock data (JSON, static arrays, DB seed scripts) without needing real backend integrations - Fast, self-directed, and a clear communicator who can send async progress updates - Bonus: experience polishing SaaS dashboards for sales demos or investor pitches
