I will build low latency voice ai agents with vapi retell and database sync
Level 2
About this gig
Most voice bots fail because blocking REST calls push latency past 600ms, breaking natural conversation flow. I build production-grade voice infrastructure using Vapi and Retell AI, optimized for real-time streaming and asynchronous database synchronization.
Technical Focus
- Low-Latency Streaming: WebSocket audio pipelines paired with Cartesia/ElevenLabs to guarantee sub-600ms response times.
- Asynchronous DB Sync: Non-blocking Python/Asyncio webhooks to query and commit data (Supabase, Postgres, CRMs) mid-call without audio freezing.
- Advanced State Control: Fine-tuned silence detection, custom interruption handling, and multi-agent routing (Vapi Squads).
- Backend Orchestration: Secure n8n pipelines for complex post-call actions and enterprise routing.
Production Stack
Vapi | Retell AI | Python (Asyncio) | Redis | Supabase | Postgres | n8n
Note: I do not build cheap wrappers or outbound spam tools. All systems are modular, documented, and 100% transferable to your own server infrastructure.
