Overview
As Lead Software Engineer on a team of 3, I architected and built a high-performance gaming portal hosting over 2000 casual and HTML5 games. The platform needed to handle traffic spikes, deliver games quickly across global audiences, and provide a seamless mobile experience while preparing for future cryptocurrency payment integration.
The Challenge
Create a high-performance gaming portal hosting 2000+ games with cryptocurrency payment integration plans.
- Initial page loads took 4+ seconds due to unoptimized game thumbnails and metadata
- Game iframe loading caused layout shifts and poor Core Web Vitals scores
- Mobile users represented 60% of traffic but had poor touch controls
- Existing architecture couldn't handle concurrent user spikes during promotions
Technical Approach
- Implemented ISR (Incremental Static Regeneration) with Next.js for game catalog pages
- Built lazy-loading system with blur placeholders for 2000+ game thumbnails
- Created responsive game container with touch-optimized controls overlay
- Designed edge caching strategy using Vercel's global CDN
Key Decisions
Next.js ISR over traditional SSR
Static generation with revalidation balanced freshness with performance
Vercel Edge Network over custom CDN
Zero-config global distribution with automatic cache invalidation
Radix UI for accessibility
Gaming audience includes users with disabilities - accessibility is not optional
Results
- Page load time reduced from 4s to under 2s (50% improvement)
- Core Web Vitals scores improved to green across all metrics
- Platform handles 3x previous concurrent user capacity
- Mobile bounce rate decreased by 35% after touch optimization
Lessons Learned
- Image optimization is often the lowest-hanging fruit for performance
- ISR is powerful but requires careful cache invalidation strategy
- Mobile-first isn't just responsive design - it's rethinking interactions
