Build MVP for a Lead Generation SaaS Platform (Real Estate / Infonavit)

Build MVP for a Lead Generation SaaS Platform (Real Estate / Infonavit) I'm looking for an experienced Full Stack Developer to build the MVP of a startup I'm launching in Mexico. About the project The goal is to create a web platform that helps people determine whether they may qualify for a home purchase using Infonavit (Mexico's housing financing system). This is not a real estate listing website. The platform's main purpose is to generate, qualify and distribute high-quality leads to real estate advisors automatically. User Flow User arrives from Facebook Ads, Google, Instagram or TikTok. User answers a short questionnaire. The platform estimates their purchasing profile. The lead is automatically classified. The lead is stored in the database. The lead is assigned to a sales advisor. The advisor receives the lead with all relevant information. The user is shown homes that match their estimated purchasing power. MVP Features Modern landing page Responsive design (mobile first) Multi-step questionnaire Lead scoring/classification Admin dashboard Authentication Lead management Automatic lead assignment Property management panel Search and filters WhatsApp integration Database Basic analytics Secure architecture Scalable codebase Tech Stack (Preferred) Next.js React TypeScript Node.js PostgreSQL Supabase Tailwind CSS If you believe another stack would be significantly better, I'm open to suggestions. Future Vision This MVP is only Phase 1. The long-term vision is to build a SaaS platform that can later support: Infonavit FOVISSSTE Bank mortgages Land purchases Used homes Custom home construction Eventually, the platform may be offered to multiple real estate developers as a subscription service. What I'm Looking For I'm looking for someone who can: Build clean and scalable code. Think beyond coding and suggest technical improvements. Communicate clearly. Work on a long-term project. Help make technical decisions. Please include: Similar projects you've built. Recommended tech stack. Estimated timeline. Estimated budget. How you would approach this project. I'm looking for a long-term collaboration, not just someone to build a website.
