Overview
SpaceBrain is my own product: a platform where businesses spin up an AI receptionist that answers their phone around the clock — takes bookings, answers questions from a knowledge base, and hands off to humans when it should.
It's not a demo. It answers live calls for real businesses in Canada, the USA, and Thailand, in English and Thai.
What it does
- Voice agents on real phone lines — low-latency speech-to-speech conversations over telephony, with barge-in handling and graceful fallbacks.
- RAG knowledge bases — businesses upload their docs and the agent answers from them, with grounding rather than guessing.
- Bookings & actions — the agent doesn't just chat; it books appointments and captures structured leads.
- Full SaaS layer — onboarding, Stripe billing, usage metering, affiliate tracking, an admin dashboard, and an embeddable web chat widget.
My role
Founder and engineer. I built and run the whole system: the voice pipeline, the backend, the Next.js dashboard, billing webhooks, deployment, and observability. Running a 24/7 voice product teaches you very quickly where distributed systems actually fail — webhook races, queue backlogs, replay attacks, latency budgets measured in milliseconds.
Why it matters for your project
If you're considering an AI product, I've already paid the tuition: prompt design, RAG quality, latency engineering, cost control, and the operational reality of LLMs in production.
