rexlead

rexlead is a lead intake and qualification system built around a real client acquisition workflow.

It started as a practical way to improve my own inbound process for AI systems, workflow automation, and software engineering work. The project grew into a full stack exercise in CRM integration, workflow orchestration, structured LLM output, and production deployment.

What it does

rexlead captures project briefs from a public site, enriches and scores them, routes them through an orchestration layer, syncs the result into HubSpot, and sends a branded first reply for qualified leads.

Architecture

The system is split across five layers.

1. A Next.js application serves the public site, protected admin views, and internal workflow endpoints.
2. Supabase handles authentication, persistence, audit records, and workflow state.
3. Ollama Cloud provides structured lead analysis with a bounded tool calling loop.
4. n8n coordinates intake, analysis, routing, replay, and scheduled digest execution.
5. HubSpot acts as the CRM layer for contacts, companies, deals, tasks, and notes.

• TypeScript
• Supabase
• Ollama Cloud
• n8n

• Nodemailer and Resend
• Vercel

Core workflow

1. A visitor submits a project brief.
2. The application validates and stores the lead.
3. n8n dispatches analysis and routing.
4. The analysis layer produces structured signals and a reply draft.
5. The routing layer updates HubSpot and logs delivery state.
6. The admin surface remains available for monitoring, resend actions, and visibility into workflow traces.
