Full Stack Developer (React, Node, TypeScript, Supabase)

We have a fully built real estate & rental management platform (React + TypeScript + Supabase, 200+ DB tables, live in production). We need an AI engineer to build and integrate the AI layer — the "brain" of the platform.

WHAT YOU'LL BUILD:
1. 3-Layer AI Architecture:
• Platform Brain — central AI that oversees all data across multiple companies
• 7 Department AI Agents — each with its own expertise (Investment, Sales, Finance, HR, Marketing, Operations, Leads), unique system prompts, and scoped database access
• Employee Personal AI — learns each employee's communication style over time, auto-replies to messages, drafts emails in their voice, gets smarter with every interaction

2. AI Features:
• Auto-fill property listings from just an address (AI generates descriptions, neighborhood info, nearby transport, amenities)
• AI Chat widget for website visitors (multilingual: EN/ES/HE)
• AI Meeting system — summarizes video meetings, extracts action items, runs "AI Agent Meetings" where all 7 agents discuss strategy using real company data
• AI Competitor tracking — auto-analyzes competitor websites and social media
• Content generation for marketing (text, social posts, suggestions)

3. API Integrations:
• Claude API (Anthropic) — primary LLM
• ElevenLabs — voice generation
• Vector embeddings with pgvector (built into our Supabase)
