CPI Learning Platform

An enterprise LMS built from scratch — SAML SSO, AI chatbot (Anthropic Claude), Twilio SMS, email campaigns, lead CRM, Stripe payments, and multi-language support.

01. The Challenge

CPI delivers professional development programmes for project management practitioners. They needed a sophisticated, enterprise-grade platform built entirely from scratch — handling everything from course delivery and certification to lead CRM, email campaigns, SSO integration with corporate clients, an AI-powered chatbot assistant, and multi-language support.

02. The Solution

I built the complete CPI platform from the ground up: a full-stack React/Node.js SPA with a PostgreSQL database, comprehensive REST API, and integrations across Stripe, Microsoft Graph, SAML SSO, Twilio, and Anthropic AI.

• Structured courses with video content, interactive exercises, knowledge assessments, and PDF certificate generation
• Authentication: email/password with bcrypt, JWT (HTTP-only cookies), SAML SSO, magic links, Google/Microsoft OAuth
• Stripe Checkout with one-time and subscription pricing, organisation seat purchases, and bulk discount tiers
• Mailchimp-style email campaign system with multi-step email chain builder and unsubscribe compliance
• Lead CRM with tag system, communications inbox, manual note logging, and automated inactivity nudge emails
• Anthropic Claude AI chatbot with page context awareness and daily digest of conversations
• i18next internationalisation with browser language detection

03. The Outcome

A comprehensive enterprise learning platform serving project management professionals, with all features live and ongoing feature development continuing.
