AiVox

Architected and built AiVox end-to-end — a production, multi-tenant SaaS platform that gives businesses an always-on AI voice agent capable of answering inbound phone calls, booking appointments, and resolving customer enquiries autonomously, with no human operator required. The platform runs on Next.js and TypeScript on the frontend, with Supabase (PostgreSQL, authentication, and row-level security) and a Node.js API layer on the backend.

Every business signs up, selects a plan, and configures its own AI agents through a no-code builder — defining the agent's persona and instructions, choosing a voice and language model, setting a greeting and call behaviour, and uploading knowledge-base documents. Agents answer around the clock, greet callers naturally, understand intent, and ground their responses in the business's own uploaded documents rather than guessing — dramatically reducing incorrect answers.

Delivered the complete self-serve SaaS lifecycle: a guided onboarding wizard that provisions an agent and phone number, subscription billing with free trials and multiple plan tiers, real-time usage metering (calls, minutes, and cost), and plan-gated feature access. PostgreSQL row-level security isolates each tenant's data, while a role-based admin console lets operators manage users, packages, model access, telephony settings, and platform-wide analytics.

Built rich post-call intelligence: every call is captured with its transcript, an AI-generated summary, duration, cost, and audio recording, surfaced in a searchable call-logs view and an analytics dashboard showing success rates, call-volume trends, and per-agent performance. Recordings stream securely with strict per-tenant access control.

Implemented advanced, plan-gated agent capabilities — automated appointment booking that texts the caller a booking link mid-call, live transfer of a call to a human team member on request, and Google Calendar integration for scheduling. Each capability is wired into the agent's behaviour automatically when enabled, and the whole app is tuned for performance with edge middleware, local JWT verification to remove authentication latency, and subscription-aware route protection.
