1.Executive Summary

An Online Learning Platform that enables educators, trainers, and businesses to create and sell video-based courses with structured curricula, interactive quizzes, progress tracking, and completion certificates. Built with Next.js for a fast, responsive learning experience, PostgreSQL for reliable progress data, and integrated video hosting via Mux or Cloudflare Stream for adaptive bitrate streaming. The platform supports the complete course lifecycle: from authoring with a drag-and-drop course builder, to student enrollment and payment via Stripe, to learning delivery with progress persistence, to completion with certificate generation. Course creators get analytics on student engagement, completion rates, and revenue. Students get a beautiful learning interface with note-taking, bookmarks, and discussion forums.

  • Drag-and-drop course builder with multimedia lesson support
  • Adaptive bitrate video streaming via Mux or Cloudflare Stream
  • Interactive quizzes with multiple question types and auto-grading
  • Progress tracking with resumable learning and bookmarks
  • Completion certificates with unique verification URLs
  • Creator analytics dashboard with engagement and revenue reports

2.Problem Solved

The online education market is projected to reach $350 billion by 2025, yet course creators face significant barriers: Udemy takes 63% of revenue on discounted courses, Teachable charges $99/month for basic features, and self-hosting requires managing video infrastructure, payment processing, and student management separately. This platform solves the problem by providing an affordable, fully-featured alternative where course creators own their content, keep their revenue (minus payment processing), and have full control over pricing, branding, and student relationships. The platform handles the complex technical challenges—video hosting, progress tracking, quiz grading, certificate generation—so creators can focus on making great content.

  • Udemy takes 63% revenue share on discounted courses
  • Teachable charges $99+/month for essential features
  • Self-hosting requires managing video CDN, payments, and student data
  • No affordable platform combines course building, video, and quizzes
  • Course creators lose student data and relationships on marketplaces
  • Existing solutions lack built-in certificate generation and verification

# Using Mux npm install @mux/mux-node # .env.local MUX_TOKEN_ID=your-token-id MUX_TOKEN_SECRET=your-token-secret # Create Mux upload for direct video upload # Configure webhook for video ready events
2

Build Course Builder

Create the drag-and-drop course curriculum editor with sections and lessons.

npm install @dnd-kit/core @dnd-kit/sortable # Build components: # - CourseBuilder with drag-and-drop # - LessonEditor for video/text/quiz # - SectionManager for organizing # - Preview mode for testing
3

Implement Progress Tracking

Build the progress tracking system that persists student advancement through courses.

# Progress tracking logic: # - Track video position every 10 seconds # - Mark lesson complete on 90% watched # - Calculate course progress from lesson completion # - Resume from last position on return
4

Create Certificate System

Build PDF certificate generation with unique verification codes.

npm install @react-pdf/renderer # Certificate features: # - Customizable template with instructor info # - Unique verification code per certificate # - QR code linking to verification page # - PDF generation and download
5

Deploy to Production

Deploy the platform to Vercel with custom domain and monitoring.

vercel --prod # Configure: # - Custom domain for student-facing pages # - Vercel Analytics for performance # - Sentry for error monitoring # - Mux webhook URL for video events

22.Common Mistakes

1

Not tracking video progress frequently enough

Consequence: Students lose their position when they close the browser or experience a network issue. Frustrating experience leads to abandonment.

Fix: Save video position every 10-15 seconds using a heartbeat API. Store position in both localStorage (client) and database (server). Sync on reconnection.

2

Making quizzes too long or difficult

Consequence: Students skip quizzes or guess answers to progress. Low engagement with assessment content defeats the learning purpose.

Fix: Keep quizzes to 5-10 questions. Provide instant feedback with explanations. Allow retakes with different question sets. Make quizzes optional for course completion.

3

Not optimizing video for mobile

Consequence: Students on mobile devices use excessive data or experience buffering. Poor mobile experience loses the 60% of learners who use phones.

Fix: Use adaptive bitrate streaming via Mux. Offer quality selection (360p, 720p, 1080p). Implement data saver mode. Compress thumbnails and images.

4

Overcomplicating the course builder

Consequence: Instructors struggle to create courses because the builder is confusing. Low course creation volume limits platform growth.

Fix: Start with a simple linear curriculum builder. Add advanced features (drip content, prerequisites) as optional settings. Provide templates for common course structures.

5

Not handling certificate edge cases

Consequence: Students who complete most but not all lessons expect certificates. Partial completion creates confusion and support requests.

Fix: Clearly display completion requirements before course start. Show progress percentage prominently. Send email when nearing completion. Offer partial certificates for 80%+ completion.

23.Frequently Asked Questions

How do students resume where they left off?
When a student plays a video, their position is saved every 10 seconds to the database. If they close their browser or switch devices, they can return to the exact same position. Progress is synced across all devices in real-time.
Can I offer courses for free?
How are certificates generated?
When a student completes all required lessons and passes all quizzes, a PDF certificate is automatically generated with their name, course title, completion date, and a unique verification code. The certificate includes a QR code that links to a public verification page.
What video formats are supported?
The platform supports MP4, MOV, AVI, and WebM uploads. Videos are processed by Mux or Cloudflare Stream and converted to adaptive bitrate formats for optimal streaming. External YouTube and Vimeo URLs are also supported.
Can students take notes while watching?
Yes. Students can add timestamped notes at any point during a video lesson. Notes are linked to the exact video position. Students can search their notes, export them, and optionally share with other students.
How do quizzes work?
Quizzes can be added to any lesson. They support multiple choice, true/false, and fill-in-the-blank questions. Quizzes are auto-graded with instant feedback. Instructors can set passing scores, time limits, and maximum attempts.

26.Scaling Strategy

The learning platform scales through CDN-cached course content, database read replicas for analytics, and video streaming handled by Mux or Cloudflare Stream infrastructure. Course landing pages are statically generated and served from edge locations globally. The course player uses client-side rendering for smooth interactivity while video streaming is handled by dedicated infrastructure.

Progress tracking scales through debounced API calls that batch position updates. Quiz submissions use background job queues for grading. Certificate generation is asynchronous with download caching. Analytics queries use pre-aggregated daily tables for fast dashboard loads.

  • Statically generated course landing pages for global CDN performance
  • Mux/Cloudflare Stream handles video encoding and delivery at scale
  • Debounced progress tracking reduces API calls by 90%
  • Pre-aggregated analytics tables for fast dashboard rendering
  • Background job queues for quiz grading and certificate generation
  • Database partitioning by course_id for data isolation
  • Redis caching for course metadata and enrollment status

27.Deployment Guide

Vercel (Recommended)

Deploy with `vercel --prod`. Set environment variables for Supabase, Mux, Stripe, and SendGrid. Configure custom domain. Enable edge caching for course pages.

Docker

Self-hosted deployment with docker-compose. Includes PostgreSQL and application containers. Suitable for institutions requiring on-premise video hosting.

Railway

One-click deploy with managed PostgreSQL. Simplified configuration for quick launch. Good for instructors who want minimal technical overhead.

AWS (Advanced)
