LiveChatAI — LLM support agent

An LLM-powered customer-support product: train it on your content, let it answer your customers. Shipped from zero to launch in under two months with a team of seven, while establishing the engineering culture — coding standards, review practice — around it.

Built on Next.js, LangChain, and Postgres. The database later moved from Vercel Postgres to Neon, which taught its own lessons about managed platforms and the value of going direct to the source.
