EdTech Learning Management & Course Platform

Project Context & Business Overview

A premier professional training academy required an end-to-end e-learning platform to deliver live and recorded technical courses, track student progression, administer automated assessments, and issue verifiable digital completion certificates.

The Problem & Operational Inefficiencies

01.

The client relied on fragmented third-party tools (Zoom links, email attachments, Google Drive folders), causing student confusion.

02.

Instructors spent dozens of hours weekly manually grading quizzes and issuing PDF certificates.

03.

Video streaming struggled on low-bandwidth connections, leading to student complaints and refund requests.

Core Engineering Requirements

  • Single centralized student dashboard with module progression tracking and bookmarking.
  • Adaptive video playback supporting low-bandwidth connections across mobile devices.
  • Automated evaluation for multiple-choice and code-submission assessments with immediate scoring.
  • Cryptographically verifiable PDF certificate generation with unique QR codes for LinkedIn sharing.

The Architectural Solution

Constructed a full-featured web application using Next.js with localized caching and protected student routes.

Integrated HLS adaptive video streaming via Cloudflare Stream to guarantee buffer-free video playback across varying network speeds.

Engineered an automated certificate engine using Node.js `pdf-lib` that renders customized high-resolution certificates with verifiable verification URLs.

Key Features & Capabilities Delivered

Adaptive Video Streaming Player

Automatically adjusts video resolution between 360p, 720p, and 1080p based on student network bandwidth in real time.

Automated Assessment & Instant Grading

Dynamic quiz modules that calculate scores immediately and provide detailed feedback explanations.

Verifiable Digital Credentials

Generates tamper-proof PDF certificates with individual verification URLs and 1-click LinkedIn Add-to-Profile integration.

Key Implementation Details

💡 Optimized database queries with Prisma connection pooling, allowing thousands of concurrent students to take exams simultaneously.
💡 Implemented offline lesson caching for text notes and downloadable study resources.

Engineering Learnings & Takeaways

Gamified progress bars and immediate assessment feedback significantly enhance student motivation and completion rates.

Adaptive bitrate video delivery is essential when serving learners outside major metropolitan fibre networks.
