AI Agents, Chatbots & Voice Agents
AI agents and chatbots that work inside your business
I build AI assistants that do real operational work: qualify inbound leads, answer customer questions strictly from your verified documents (RAG), book appointments over the phone by voice, and write structured data straight into your CRM. No fragile prompt toys — everything is built with guardrails, deterministic tool calling, and full audit logs.

06 — FAQ
AI Agents, Chatbots & Voice Agents: questions
Can the chatbot answer questions strictly from my own business data?
Yes. I connect it to your documents, website and database using hybrid retrieval (RAG with PostgreSQL pgvector), so answers come strictly from your verified information rather than generic AI guesses.
Do you build AI voice agents for inbound and outbound phone calls?
Yes — I build low-latency voice agents using Vapi, Retell, OpenAI and Twilio that answer calls 24/7, qualify leads, book or reschedule appointments on your calendar, and transfer to a human when needed.
Will the AI agent connect to my existing CRM and calendar?
Yes. Every qualified lead, call summary, and booked appointment syncs automatically into HubSpot, GoHighLevel, Monday.com, Salesforce, Zoho, Google Calendar, Cal.com, or a custom database.
How do you prevent the AI from hallucinating prices or policies?
By combining strict system prompt boundaries, low temperature, hybrid vector + keyword retrieval, and structured tool schemas. If a caller asks something outside the approved knowledge base, the agent escalates cleanly to your team.
