ChatCore is a full-stack SaaS product that lets any business add an AI-powered chat widget to their website with a single script tag. It's built solo, end to end — architecture, backend, frontend, and live deployment.
A React-based admin dashboard lets the business manage widget configuration, review conversation history, and view analytics. Under the hood, the Groq API powers context-aware, real-time responses (migrated from Gemini after hitting free-tier rate-limit errors), while the backend runs on Node.js/Express with a PostgreSQL (Neon) database — including diagnosing and fixing a production connection-pool bug affecting live traffic.
ChatCore is integrated directly into the DelVoxe agency site as a live working demo, and is used as the primary proof-of-work when pitching full-stack and AI integration work to freelance clients.
