Project description:
"Objective

Build a WhatsApp automation system that handles incoming leads, converses naturally, and delivers psychologically persuasive scripted responses. The system must appear 100% human to end users (undetectable as AI), and must integrate with payment systems for $350 consultations.

⸻

Core Requirements
1. WhatsApp Automation
• Connect via Twilio WhatsApp API or 360Dialog (Meta BSP).
• Handle 200–1000+ inbound leads/day.
• Multi-number support (scalable, avoid account blocks).
2. Human-like AI Conversation
• Messages must be indistinguishable from human text.
• Include typing delays, pacing, emojis, and contextual memory.
• Must allow integration with various AI APIs (OpenAI, Anthropic, etc).
• Undetectable → no “AI disclaimers,” no bot-style formatting.
3. Admin Configuration Screen
• Secure login for admin.
• Input & manage multiple API keys (e.g. OpenAI tokens).
• Editable seed prompt / system prompt for the AI personality.
• Upload/edit response templates (pre-written scripts).
• Dashboard: leads per day, conversion %, payments received.
4. Payment Integration
• When user reaches paywall → send auto payment link.
• Must support:
• MercadoPago (QR or link)
• Stripe MX
• PayPal
• SPEI transfers (automatic generation of CLABE or reference code, webhook to confirm payment)
• After payment confirmed → unlock “full consultation flow.”
5. Message Flow
• Greeting → ask name + issue → keyword detection.
• AI or scripted deep diagnostic response.
• Trigger payment link.
• After payment → deliver full consultation (scripted/AI mix).
6. Scalability
• Must handle up to 1000 leads/day.
• Architecture: reliable, containerized (Docker preferable).
• Logs + monitoring for performance.

⸻

Deliverables
• Full codebase (Node.js or Python preferred).
• Admin dashboard (React, Vue, or similar).
• Documentation + setup guide.
• One-time setup on VPS (Hetzner / DigitalOcean / AWS).

⸻

Skills Required
• Experience with WhatsApp Business API (Twilio, 360Dialog).
• Strong backend development (Python/Flask/FastAPI or Node.js/Express).
• Frontend for admin panel (React/Vue).
• Familiar with AI API integration (OpenAI, Anthropic, or similar).
• Payment gateways: MercadoPago, Stripe, PayPal, SPEI (via OpenPay/Conekta or banking API).

⸻

Notes
• Must be undetectable as AI to end users.
• Include typing simulation, delays, and natural flow.
• Must be modular: easy to swap APIs or edit seed prompts.
• Long-term cooperation possible for scaling and updates." (client-provided description)
