Built with Modern Web Technology
This application showcases what's possible with modern web standards and performance optimization:
- Client-Side Database: SQL.js brings SQLite to your browser for instant data queries
- Responsive Charts: Chart.js creates smooth, interactive visualizations that work on any device
- Modern CSS: Tailwind CSS v4 powers the responsive design and dark mode
- Zero Backend: Everything runs in your browser—fast, private, and offline-capable
- Performance Optimized: Deferred script loading, resource preconnection, and optimized DOM operations for fast page loads
- SEO Enhanced: Structured data markup, comprehensive meta tags, and hash-based routing for better discoverability
- Production Ready: Minified assets with Gzip and Brotli compression for optimal delivery
An AI-Assisted Development Story
This project was created as an exploration of AI-assisted software development. From data extraction to UI design, performance optimization to SEO implementation, AI agents helped plan, code, test, and refine every aspect of the application. The result demonstrates how AI can accelerate development while maintaining code quality and user experience standards.
The development process included automated web scraping of historical lottery data (using Go), database design and optimization (SQLite generation), responsive UI implementation (Tailwind CSS v4), performance tuning (deferred loading, DOM optimization), SEO enhancement (structured data, meta tags, URL routing), and production build optimization (minification, compression)—all coordinated through agentic workflows that combined human direction with AI execution.
