I will build an ai whatsapp agent with chatgpt and CRM integration
Igor N
About this gig
Stop losing sales because your WhatsApp leads go unanswered after hours.
Customers hate traditional "Press 1 for Sales" chatbots. They want immediate, human-like responses. If you rely on basic rule-based bots, you are frustrating your clients and losing money. You need an Autonomous AI Sales Agent that understands context, closes deals 24/7, and saves the data directly into your CRM.
I am a Senior Software Architect with 20+ years of engineering experience. I don't build generic chatbots; I architect intelligent AI systems using Python, n8n, and LLMs (ChatGPT/Claude).
What I bring to your project:
- Human-Like AI: Bots that understand natural language and intent, not just keywords.
- Context Guardrails: Strict business rules to ensure the AI NEVER hallucinates, invents prices, or promises what you can't deliver.
- Knowledge Base (RAG): The AI will read your private PDFs, pricing tables, and websites to answer perfectly.
- CRM & Calendar Sync: Automatic lead qualification and routing directly to HubSpot, Pipedrive, Salesforce, or scheduling via Calendly.
- Human Handoff: Seamlessly transfer the chat to a human agent when needed.

FAQ
Can the AI answer questions based on my company's specific PDFs and pricing?
Yes. Using RAG (Retrieval-Augmented Generation) and Vector Databases (Pinecone), I train the AI on your exact documents so it acts as an expert on your specific business, without making up answers.
Can the AI understand Audio/Voice messages on WhatsApp?
Absolutely. I can integrate the OpenAI Whisper API into the architecture. The system will transcribe the customer's audio, process the intent with the LLM, and reply contextually.
Which CRMs can you integrate the WhatsApp bot with?
As a Senior Backend Engineer, I can connect via REST API or Webhooks to almost any modern system, including HubSpot, Pipedrive, Salesforce, Monday.com, Zoho, ActiveCampaign, and customized internal databases.
Can the bot schedule meetings or appointments?
Yes. I can integrate the AI agent with Google Calendar, Calendly, or your custom booking system, allowing the bot to check your availability and schedule meetings autonomously.
What happens if the AI doesn't know the answer or the customer gets angry?
I implement a "Human Handoff" routing rule. If the AI detects frustration or if the user asks for a human, the bot pauses automatically and notifies your sales team on your dashboard (like Chatwoot or similar) to take over the chat.
Will I have to pay expensive monthly per-message fees to SaaS platforms?
No. By building a custom architecture (using n8n or Python backends), you avoid abusive SaaS platform fees. You only pay for your server (VPS) and the direct API usage from OpenAI/Claude, saving thousands of dollars a year.
Can you integrate this with Facebook Messenger and Instagram Direct too?
Yes. Using the Meta Graph API, we can deploy the same AI "brain" to answer leads coming from Instagram Reels, Facebook Ads, and Messenger, unifying your whole sales pipeline.
Why must I contact you before placing an order?
Integrating AI with your CRM requires an audit of your current tech stack. I need to understand your sales funnel to guarantee the architecture will be perfectly tailored to your business rules.
