I’ve already built production Twilio-based communication systems, including Twilio Voice, Media Streams, webhooks, and real-time audio pipelines. This isn’t new ground for me. For InboxxHQ, I would design and build the AI communication engine across SMS, WhatsApp, and live voice calls, using a clear state machine + intent routing + memory layer, not a free-form chatbot. I’ve implemented real-time call flows where audio streams from Twilio into speech-to-text, passes through an LLM for reasoning, and returns as natural speech with proper fallback and recovery logic. My focus is on low latency, reliability, and scale — handling dropped audio, retries, model fallbacks, and clean observability. I build systems that survive real traffic, not just demos. I’m comfortable owning both the architecture and the implementation and delivering against the Week 1 / Week 2 timeline you outlined.
