Technical Highlights
Serverless-First Architecture
Designed the entire backend to run on Cloudflare's global edge network, eliminating traditional server management while achieving <50ms P95 response times. The architecture automatically scales to handle traffic spikes without manual intervention or capacity planning.
Sophisticated Caching Strategy
Implemented a three-layer caching system:
- Edge Cache (Cloudflare): TMDB responses cached at 300+ global data centers with content-specific TTLs (15m for trending, 24h for details, 7d for configuration)
- Client Cache: In-memory cache with automatic invalidation and stale-while-revalidate for instant UI updates
- Request Deduplication: Prevents duplicate API calls during concurrent component renders
Security & Privacy
- All TMDB API calls proxied through backend to hide credentials and enforce rate limits
- JWT tokens with short expiration (1 hour) and automatic rotation
- HttpOnly cookies for refresh tokens to prevent XSS attacks
- SHA-256 token hashing for stored credentials
- Rate limiting with sliding window algorithm to prevent abuse
- No raw email logging in analytics events
Database Design
Normalized schema with 8 tables optimized for edge database constraints:
- Efficient indexing strategy for common query patterns
- Foreign key constraints with cascade deletes for data integrity
- Composite primary keys for many-to-many relationships
- Timestamp-based audit trails on all user actions
Type Safety Throughout
- Shared TypeScript interfaces between frontend and backend
- Strict null checking and no implicit any
- Discriminated unions for API response types
- Compile-time validation of environment variables
Error Handling & Resilience
- React Error Boundaries catch component failures gracefully
- Automatic retry logic with exponential backoff for failed requests
- Toast notification system for user-facing error messages
- Comprehensive logging for debugging and monitoring

Notable Implementations
Guest Browsing Mode
Engineered a dual-mode experience where unauthenticated users can browse the full catalog without login, while authenticated users gain access to personalization features. The system seamlessly transitions between modes, prompting login only when attempting protected actions.
Magic Link Authentication
Built a complete passwordless authentication flow with single-use tokens, configurable expiration, and rate limiting. The system enforces resend cooldowns, tracks IP/user-agent fingerprints for security auditing, and provides automatic session refresh without user intervention.
Infinite Scroll with Prefetching
Implemented intelligent infinite scroll that prefetches the next page when users approach the scroll threshold, creating the illusion of instant content availability. The system handles edge cases like rapid scrolling, failed requests, and race conditions.
Shimmer Loading States
Designed skeleton loaders that mimic the actual content structure, providing visual continuity during data loading. The shimmer animation respects prefers-reduced-motion for users with motion sensitivity.
Optimistic UI Updates
Applied optimistic updates for user actions (ratings, My List additions) to provide instant feedback. The system maintains a rollback queue to revert changes if the backend request fails, preserving data consistency.
