About
I am the founder of a startup building a two-sided B2B marketplace platform. I have a complete Product Requirements Document (PRD) and high-fidelity Figma designs for every screen and user flow. I am looking for a Senior Full-Stack Partner (or boutique agency) to execute the build. I am not looking for a "code monkey" who simply follows instructions; I need a technical partner who will challenge my assumptions and provide critical input on architecture, security, and scalability. The Approach: "High-Efficiency Frontend, Bulletproof Backend" We are prioritising speed and robustness. Frontend: I expect you to use modern acceleration workflows (e.g., Locofy, Cursor, AI-assisted boilerplate) to convert my Figma designs into Next.js/Tailwind code efficiently. Backend: I expect the bulk of the budget and effort to go into manual, high-security coding of the complex integrations (Stripe Connect Escrow, Identity Verification, and Data Privacy). The Project Scope: User Roles: Service Providers (Businesses) vs. Clients (Organisations) vs. Admin. Core Features: Stripe Connect Embedded: Split payments, escrow holding, and complex payout schedules. Verification: Google Business Profile API integration to verify the authenticity of Service Providers. Messaging: In-app chat (Sendbird integration) with image support and negotiation flows. Search/Discovery: Geo-location based search to find providers within a specific radius. Required Tech Stack: Frontend: Next.js (App Router), TypeScript, Tailwind CSS. Backend/DB: Supabase (PostgreSQL) OR Node.js with a standard SQL database. Infrastructure: Vercel or AWS.
