Build AI Platform for Real Estate

Job Details

Description

Summary # Upwork Job Posting – AI SaaS Developer (MVP) I am the founder of Pro Level Negotiation (PLN), a real estate negotiation training company operating in both New Zealand and the United States. Over the past 20+ years I have developed a proprietary negotiation methodology specifically for real estate professionals. I have already built and tested an advanced AI assistant using ChatGPT that agents are using successfully. I am now looking for an experienced developer to build Version 1 of a standalone subscription platform. This is **not** simply a chatbot. It is an AI-powered negotiation assistant designed specifically for real estate professionals. The successful applicant will ideally have experience building AI SaaS platforms using the OpenAI API. --- ## Project Objective Build a secure web application where paying subscribers can log in and access the PLN AI Assistant without requiring them to use ChatGPT directly. The platform should feel like a professional SaaS product. --- ## Core Features Required ### Secure User Accounts * User registration * Login/logout * Password reset * User dashboard * Profile management --- ### Subscription Management * Monthly subscription * Annual subscription (optional) * Stripe integration (or another payment provider if required) * Automatic renewals * Cancel subscription * Failed payment handling --- ### AI Chat Interface A clean conversational interface similar to ChatGPT where users can ask negotiation questions. The AI should use my proprietary negotiation methodology through carefully structured system prompts and knowledge files. Users should never have access to these prompts. --- ### Knowledge Base The platform should allow me to upload and manage: * PDF files * Word documents * Negotiation frameworks * Prompt instructions * Templates I need to be able to update these resources without rebuilding the application. --- ### Prompt Orchestration The application should automatically inject my negotiation methodology into every conversation before responding. The user should not see these prompts. --- ### Conversation History Users should be able to: * View previous conversations * Rename conversations * Delete conversations --- ### Usage Limits Admin should be able to control: * Monthly message limits * Usage tracking * Subscription levels (future) --- ### Admin Dashboard I need an administrator area where I can: * View subscribers * Disable accounts * Update prompts * Upload new resources * View usage * Send announcements * Manage subscriptions --- ### Branding The application should use Pro Level Negotiation branding rather than ChatGPT branding. --- ## Future Features (Not Required for MVP) The architecture should allow future expansion including: * Negotiation Plan Builder * Vendor Report Generator * Buyer Psychology Assessment * Listing Strategy Builder * Certification Portal * Video Library * Live Coaching Calendar * CRM integration * Mobile application --- ## Preferred Technology Stack I am open to recommendations. Ideally something modern and scalable. Examples include: * React or Next.js * Node.js * Supabase or Firebase * PostgreSQL * OpenAI API * Stripe * Vercel or AWS However, I am open to better suggestions if they simplify maintenance. --- ## What I'm Looking For * Experience building AI applications using OpenAI APIs * Experience with SaaS subscription products * Strong UI/UX design skills * Excellent communication * Ability to recommend improvements * Long-term development relationship preferred --- ## Please Include in Your Proposal 1. Examples of AI applications you have built. 2. SaaS products you have launched. 3. Your recommended technology stack. 4. Estimated timeline for an MVP. 5. Estimated budget. 6. Suggestions for improving this platform. 7. Availability for an initial planning meeting. --- ## About the Product This platform is designed to become the leading AI negotiation assistant for real estate professionals worldwide. The goal is to create a premium subscription platform that combines AI with proven negotiation frameworks, ongoing education, and continuous product development. I am looking for a developer who wants to build a long-term product rather than simply complete a one-off project.
