Timeline

## Project Overview Timeline is a mobile social networking application that reimagines how users create and consume content. Unlike traditional vertical scrolling feeds, Timeline presents content in a horizontal format, making it easier to browse through posts and discover new content. ## The Challenge Traditional social media platforms have limited post creation options and vertical feeds that can feel overwhelming. Users wanted: - More creative control over their posts - A different way to browse content - Faster content discovery - Better performance on mobile devices ## Technical Approach ### Frontend Architecture Built with React Native for cross-platform compatibility, the app features: - Custom post creation engine with 15+ layout templates - Real-time preview system for post editing - Smooth horizontal scrolling with gesture support - Optimized image loading and caching ### Backend Infrastructure The backend is built with Spring Boot and deployed on AWS: - RESTful API with JWT authentication - PostgreSQL database with connection pooling - Redis caching for frequently accessed data - AWS S3 for media storage - Docker containers orchestrated with Kubernetes ### DevOps & Deployment Implemented a robust CI/CD pipeline: - GitHub Actions for automated testing and building - Docker containerization for consistent environments - Kubernetes for orchestration and scaling - AWS EKS for managed Kubernetes service ## Key Features ### Custom Post Creation Users can choose from various post layouts including: - Photo grids (2x2, 3x3, 4x4) - Story-style layouts - Quote and text posts - Mixed media posts ### Horizontal Feed The signature horizontal scrolling feed provides: - Smooth infinite scrolling - Lazy loading for optimal performance - Gesture-based navigation - Quick post previews ### Performance Optimizations - Image compression and progressive loading - Database query optimization - CDN integration for global content delivery - Background sync for offline support ## Results & Impact The project successfully delivered on all key objectives: - **User Engagement**: 40% increase in time spent browsing content - **Performance**: 40% reduction in feed load times - **Reliability**: 99.9% uptime achieved through robust infrastructure - **Development Efficiency**: Deployment time reduced from 2 hours to 15 minutes ## Lessons Learned This project taught me valuable lessons about: - Building scalable mobile applications - Implementing complex UI interactions - Managing cloud infrastructure - Establishing effective CI/CD pipelines - Performance optimization for mobile devices ## Future Enhancements Potential improvements include: - AI-powered content recommendations - Advanced analytics dashboard - Social features (comments, sharing) - Cross-platform web version - Integration with other social platforms
