SaaS, Multi-tenant Architecture, Stripe API, Supabase (or PostgreSQL), and React.js or Next.js.

Thought process Thought process Here's a complete, ready-to-paste description for that field: Project Overview I'm building CommandREAI, a multi-tenant SaaS platform for real estate brokerages. It replaces the mix of spreadsheets, email chains, and disconnected tools that brokerages currently use to manage listings, transactions, compliance, commission disbursement, and day-to-day back-office operations. It's designed around a real, currently-used transaction coordination workflow, not a hypothetical idea. What's Already Prepared I have a complete functional specification covering every screen, field, and workflow rule across all modules, wireframe mockups of the core screens, a finalized pricing/billing model, and a full set of legal agreements (subscription terms, contractor agreements, privacy/security policies) already drafted. I'm not asking a developer to help figure out what to build — that part is done. I'm looking for someone to build it. Core Modules Transaction management, compliance review workflow, salesperson/agent tracking, internal communication tools, a brokerage resource library, a back-office admin center (billing, branding, commission processing), and a separate client-facing portal for buyers/sellers. Key Requirements Multi-tenant architecture — each brokerage's data, branding, and document templates must be fully isolated from every other brokerage. Role-based permissions across 7 different user types. Subscription + per-transaction billing through Stripe. Launches as a responsive web app (not a native mobile app — that's a planned Phase 2). Recommended Stack (open to your input here): Supabase for database/auth/file storage, Stripe for billing, Resend for transactional email, the Anthropic Claude API for AI-assisted features. How I'd Like to Work Looking for fixed-price milestones tied to specific deliverables rather than open-ended hourly billing. Please share a portfolio of comparable multi-tenant SaaS projects (not general web/marketing sites) and, if possible, a reference from another SaaS founder you've worked with. A full written project brief is ready to share with serious applicants.
