We need an AI Developer to build: 1. WhatsApp Bot (Sales Brain) . It must negotiate, cross-sell, and close deals. 2. Voice Bot for VICIdial – Handles missed calls, partner follow-ups, and automated sales calls. The bot must have "sales intelligence" including counter-offers, urgency triggers, dynamic pricing, and cross-selling logic—far beyond basic intent recognition. Key Responsibilities 1. WhatsApp Business Bot – Sales Brain (60% of effort) Intent & Entity Extraction: Detect verticals (Transport, Movers, Insurance, Real Estate) and extract fields (pickup/drop, date, vehicle type, weight, budget, property type) from free text. Conversation Management: Handle multi-turn dialogues with context retention (e.g., customer asks for price, then changes origin city). Negotiation & Closing Logic: Auto-counter offer when customer says "Price is high" (respect max discount % from dynamic config). Urgency triggers: if customer says "Comparing options", push limited-time discount. Objection handling ("I'll think", "Too costly", "Need to ask partner"). Final closing: "Shall I send a payment link to lock this price?" Cross-sell Engine: Based on primary enquiry, proactively offer relevant services (e.g., Transport enquiry → Transit Insurance). Ask "Do you also need insurance for your goods?" and capture response. Dynamic Pricing Integration: Apply multipliers for urgency (same-day = +15%), route demand, and customer profile (corporate premium). Template Management: Design and manage pre-approved WhatsApp templates (greeting, quote sent, follow-up nudge, urgency push, payment link, etc.). 2. Voice Bot for VICIdial (30% of effort) Missed Call Handler: When a customer gives a missed call, voice bot calls back within 30 seconds, asks "Which service do you need?", captures details via speech recognition, and creates a lead in Zoho. Partner Follow-up Bot: Calls transport partners who haven't responded to WhatsApp bid requests. Reads consolidated requirements aloud, asks for bid amount (e.g., "Please say your bid amount"), captures spoken number, and updates Zoho. Outbound Sales Calls: For warm leads (score > 60, no WhatsApp response in 2 hours), bot calls and attempts to close the deal. 3. Integration & Logging (10% of effort) Integrate with Zoho CRM via REST APIs (read/write leads, quotations, bids). Integrate with VICIdial via AGI scripts. Store full conversation transcripts (WhatsApp + calls) into Zoho Notes for audit trail. Technical Requirements & Stack Component Technology NLP / Intent Recognition Rasa, Dialogflow ES/CX, or custom transformers (e.g., BERT fine-tuned) WhatsApp Integration WhatsApp Business API (Meta) – via Twilio, WATI, or official API Voice Bot Google Dialogflow CX Phone Gateway / Amazon Lex + Polly / Asterisk AGI Backend Microservice Python (FastAPI/Flask) or Node.js Deployment AWS Lambda / EC2 / DigitalOcean (or any cloud) CRM Integration REST API calls to Zoho CRM (OAuth 2.0) Must-have experience: Built at least 2 production WhatsApp bots with negotiation logic. Integrated voice bots with Asterisk/VICIdial. Strong understanding of state machines for conversation flow. Experience with dynamic pricing or e-commerce bots preferred.
