Muhammad Ahmad is building their profile!
I deployed a low-latency Voice AI agent that handles front-desk phone calls, end-to-end real calls, real calendar writes, not a static chat demo.
The architecture generalizes to any business dependent on live phone calls and scheduling (clinics, salons, legal practices) anywhere a missed call means a lost customer.
The Production Stack:
• Voice Layer: Vapi + Groq (Llama-3.1) for sub-200ms token generation.
• Logic Gateway: Async FastAPI backend managing structural data validation.
• Workflow Sync: Decoupled n8n subflows to protect core server threads from third-party API downtime.
• Logs & Observability: PostgreSQL persistent decision log with a non-developer dashboard.
If your front desk runs on phone calls and you want to systematically protect your revenue lines from dropped after-hours customer calls, let's talk.
