Introduction
Built and launched the first phase of the platform from scratch, serving thousands of teachers and students globally
Designed and implemented a distributed content delivery system that handles educational resources in multiple languages and formats
Architected a microservices-based backend with intelligent caching, search optimization, and payment processing to support high-traffic loads
Features
Scalable Content Distribution Architecture
- A distributed content delivery network powered by AWS S3 and Cloudinary CDN optimizes resource loading times across multiple regions
- Multi-layer caching with Redis and application-level caching reduced server load by 50% and improved response times by double
- The microservices-based architecture handles concurrent uploads, processing, and distribution of educational resources efficiently
Advanced Search & Discovery System
- Elasticsearch powers full-text search across thousands of resources with faceted filtering by language, grade level, and subject
- Intelligent ranking algorithms with relevance to user behavior and preferences
- Real-time search suggestions and autocomplete with debouncing and caching to maintain optimal performance
Product Management & Workflow System
- The product upload system supports multiple file formats (PDFs, images, videos) with automatic validation and processing
- A content moderation workflow manages status transitions from draft to pending review, published, and archived states
- Role-based access control provides granular permissions for teachers, moderators, and administrators
Payment Integration & Subscription Management
- Stripe handles secure payment processing with webhooks managing the entire subscription lifecycle
- The subscription system supports monthly and annual plans with automatic prorated upgrades and downgrades
Performance Optimization & System Architecture
- Database queries were optimized with connection pooling to handle thousands of concurrent users smoothly
- Priority Hints API enables intelligent resource loading, significantly improving Core Web Vitals scores
- The fault-tolerant architecture includes comprehensive error handling, retry mechanisms, and graceful degradation
