Full-Stack Developer for Fintech Marketplace Similar to Paperstac

Hi there, I looked at Paperstac before writing this. The platform works, but the experience feels heavier than it needs to be. There's friction in places where a fintech marketplace should move fast: browsing listings, submitting offers, tracking deal flow. You're right to want simpler and cleaner. I've built two-sided marketplaces before, including a WooCommerce-based MVP marketplace for Pink Robin Inc. where I structured buyer and seller roles, built custom listing types with financial fields, and handled offer/counteroffer workflows. That project taught me where marketplace friction actually lives: it's not in the features, it's in how many clicks separate intent from action. For your platform, I'd approach it in stages. First, nail the core loop. User registration with role assignment (buyer/seller), profile setup, listing creation with deal-specific fields, and basic search/filtering. This is the spine. Everything else hangs on it. Second, deal flow and communication. Offers, counteroffers, and status tracking need to feel like a conversation, not a form submission chain. I'd build a unified deal dashboard where both sides see the same timeline: offer submitted, countered, accepted, documents uploaded, deal closed. Private messaging threaded by deal ID so context stays intact. Third, document handling and notifications. Secure file uploads tied to deal records, with version tracking if needed. Email and in-app notifications for every state change: new offer, counteroffer, message received, document uploaded. Fourth, admin oversight. A backend dashboard with user management, listing moderation, deal monitoring, and dispute flags if necessary. What I'd do differently than Paperstac: 1. Faster onboarding. Paperstac's registration flow feels long. I'd use progressive disclosure: get users in with email and password, then collect profile details as they need them (first listing or first offer). 2. Cleaner deal cards. Right now Paperstac's listings pack too much into the card view. I'd show only the critical numbers (asset type, price, key terms) and move everything else to the detail view. 3. Better mobile experience. Paperstac works on mobile but doesn't feel native. I'd optimize touch targets, simplify navigation, and make the deal dashboard thumb-friendly. Features Paperstac doesn't offer that would help: 1. Saved searches with alerts. Let buyers create filters and get notified when matching listings appear. This keeps them engaged without requiring daily logins. 2. Deal templates for repeat users. Sellers who list similar deals regularly should be able to save a template and duplicate it. Saves time and reduces errors. 3. Integrated deal comparison. Buyers often evaluate multiple listings. A side-by-side comparison view would make that easier and keep them on the platform longer. Tech stack I'd recommend: Frontend: React with TypeScript, Next.js for server-side rendering and SEO, Tailwind for styling Backend: Node.js with Express or NestJS, PostgreSQL for relational data (users, listings, deals, messages), Redis for caching and session management File storage: AWS S3 or similar for documents Auth: JWT-based authentication with role-based access control Deployment: Docker containers, hosted on AWS or Vercel depending on scaling needs API structure: RESTful with clear versioning, built to accept future integrations (Stripe, Plaid, DocuSign, etc.) Timeline and cost for MVP: 8 to 10 weeks for a functional MVP covering user registration, dual roles, listings, search/filter, offers/counteroffers, messaging, document uploads, notifications, dashboards (user and admin), and responsive design. Cost estimate: $18,000 to $24,000 depending on final feature scope and design complexity. I work as an individual developer, not an agency, but I collaborate with a designer when needed for mockups and can bring them in if you don't have design covered. I'm an individual developer. I've been building full-stack platforms for over 10 years, and I've worked on financial tools, marketplaces, and custom workflow systems. I contribute product ideas, not just code. If you're at the early stage and want someone who can think through UX tradeoffs and marketplace dynamics, not just implement specs, I'm set up for that. One question: do you already have branding and design direction, or are you starting from scratch on the visual side? Trust, Tai Screening Question Answers 1. Please review Paperstac before applying. Generic proposals without relevant examples and specific ideas for improving the marketplace will not be considered. I reviewed Paperstac before writing this proposal. The platform demonstrates solid marketplace fundamentals but feels heavier than necessary in navigation and deal flow. I've outlined three specific UX improvements (faster onboarding, cleaner listing cards, better mobile experience) and three features Paperstac lacks (saved search alerts, deal templates, integrated comparison view) in my proposal above. My relevant experience includes building a two-sided WooCommerce marketplace for Pink Robin Inc. where I handled buyer/seller roles, custom listing types, offer workflows, and deal status tracking. That project is directly comparable to what you're building here.
