Learning Management System

The Challenge

The client — an education provider — was managing courses through a combination of Zoom, Google Sheets, and email. Enrollment was manual, progress tracking was nonexistent, and there was no way to issue verified certificates. They needed a unified platform that could handle the full learning lifecycle from enrollment through assessment and certification, with support for both live and self-paced learning.

Our Approach

Discovery revealed that the system needed to serve three distinct user types with very different needs: administrators managing courses and instructors, instructors delivering content and grading, and students consuming content and tracking progress. Each required a tailored dashboard experience.

We built the frontend in React with role-based routing — each user type sees a completely different interface after authentication. Go was selected for the backend API layer because of its concurrency model — live class features require WebSocket connections for real-time participation, and Go handles thousands of concurrent connections efficiently.

PostgreSQL manages the relational data: courses, enrollments, grades, and certificate records where referential integrity is critical. The assessment engine supports multiple question types (multiple choice, short answer, file upload) with configurable grading rubrics and automatic score calculation.

Key Technical Decisions

WebSocket-based live classrooms. Instead of embedding a third-party video tool, we built real-time classroom features — chat, polls, hand-raising, screen sharing triggers — as a WebSocket layer. Video itself integrates with existing providers, but the interactive layer is native to the platform.

Certificate verification system. Each certificate gets a unique hash stored on-chain, allowing third-party verification via a public URL. This gives the certificates institutional credibility beyond the platform itself.

Progressive content unlocking. Course content unlocks based on completion criteria — students must pass assessments or complete prerequisites before accessing advanced modules. This is enforced at the API level, not just the UI.

The Outcome

The LMS launched in 8 weeks and now supports over 5,000 active learners across 200+ courses. Instructor adoption was rapid because the dashboard eliminated their administrative burden. The automated certificate system processes hundreds of verifiable credentials monthly. We're currently extending the platform with AI-powered content recommendations and adaptive learning paths.
