TipTop CA

TipTop CA is a fully production-grade, revenue-generating Learning Management System (LMS) that I independently designed, developed, deployed, and scaled to support 1000+ active students. The platform is engineered with a strong focus on automation, performance, scalability, and real-world business workflows.

I built a complete authentication and user management system with secure signup, login, and email verification to ensure controlled access. The platform implements role-based access control (RBAC) for Admins, Instructors, and Students, enabling structured permission handling across the system.

One of the core highlights is the fully automated onboarding workflow. After a successful first payment, the system triggers automated Microsoft Azure account creation for students, eliminating manual intervention and streamlining operations.

The payment infrastructure is deeply integrated using PayFast, supporting one-time payments, installment plans, upsells, and webhook-based verification. I implemented backend logic to handle asynchronous payment confirmations, retries, and status tracking to ensure reliability.

The student dashboard is highly dynamic and personalized, allowing users to access course content, track progress at a granular level, and monitor learning activity. The platform also includes automated notifications and certificate generation upon course completion.

On the admin side, I developed a full-featured dashboard that includes student management, course content control, payment tracking, RAG knowledge base management, and detailed analytics.

I built an AI-powered chatbot using a Retrieval-Augmented Generation (RAG) architecture. This includes processing and converting course materials into structured JSON knowledge bases, implementing intelligent context retrieval, and integrating with an AI model to deliver accurate, context-aware responses. This significantly reduces support load while improving the student experience.

From an infrastructure perspective, I handled full deployment and DevOps. The application is deployed on a Hostinger VPS with Nginx configuration and SSL setup. Process handling is managed via PM2, and I built a CI/CD pipeline for automated deployments, ensuring server stability and uptime.
