AI Voice & Chat Agents for Client Support
The Situation
The pattern behind most agent projects: businesses losing leads to missed calls and slow first responses, with no realistic way to staff round-the-clock support.
What I Did
I build AI voice and chat agents on Retell AI / Vapi, connected to CRM and messaging channels (including WhatsApp Cloud API) through n8n workflows, so inbound inquiries get an immediate, on-brand response before a human ever needs to step in.
