Building RapidWire: A Multi-Tenant CRM for Contractors

Contractors live or die by response time. Leads come in by phone, web, and email, and missing a 15-minute window can cost a job. I wanted a CRM that treats speed as a core product requirement and scales securely across many tenants.

The Problem

Service businesses face:

  • Leads scattered across channels
  • Slow response and poor tracking
  • Manual RFP matching
  • Teams that need clear permissions

The Solution

RapidWire is a multi-tenant SaaS CRM built for contractors with a 15-minute response guarantee, automated RFP processing, and strong tenant isolation.

Core Features

  • Unified lead management
  • Response-time tracking with alerts
  • RFP parsing and customer matching
  • Webhook notifications
  • Role-based access control

Technical Highlights

  • Cloudflare Workers + D1 for low-latency API
  • Next.js 15 frontend
  • Tenant isolation enforced at the database layer
  • Security hardening with JWT, PII encryption, audit logging
  • Cap'n Web RPC for headless CRM workflows

Impact

  • Faster response times for contractors
  • Automated RFP workflows
  • Secure multi-tenant scaling

What Makes It Different

Most CRMs optimize for sales teams. RapidWire optimizes for time-sensitive service businesses where response time is the competitive edge.

Tech Stack

  • Next.js 15, TypeScript, Tailwind CSS
  • Cloudflare Workers, D1
  • Cap'n Web RPC
  • JWT auth, bcrypt, audit logs

Current Status

Production Ready:

  • Multi-tenant platform operational
  • RFP parsing endpoints
  • Plugin architecture for integrations
  • 80% test coverage target achieved

What I Learned

Multi-tenant design has to be enforced everywhere, not just in a middleware layer. Security and isolation are product features, not technical afterthoughts.
