Web Performance Optimization (WPO)

Deliver blazing-fast web experiences that increase conversions, SEO rankings, and user satisfaction

Web Performance Optimization

Transform your website into a speed demon with expert web performance optimization that directly impacts your bottom line. I specialize in achieving perfect Core Web Vitals scores, reducing page load times by up to 80%, and ensuring your site performs flawlessly under peak traffic. Faster websites mean better SEO rankings, higher conversion rates (up to 20% increase), and superior user experiences that keep visitors engaged.

My comprehensive approach includes advanced caching strategies with Redis and Varnish, CDN optimization for global content delivery, database query tuning for PostgreSQL and MySQL, and Application Performance Monitoring (APM) using OpenTelemetry, New Relic, and Datadog. I analyze every aspect of your stack to identify and eliminate bottlenecks, from frontend rendering to backend database queries.

Whether you need to handle Black Friday traffic spikes, improve mobile performance, or achieve perfect Google PageSpeed scores, I deliver measurable results. From code-level optimizations to serverless architecture design, I implement solutions that make your web applications lightning-fast while maintaining code quality and user experience excellence.

Core Web Vitals Excellence

  • Perfect LCP scores (Largest Contentful Paint < 2.5s)
  • Optimal FID/INP (First Input Delay / Interaction to Next Paint)
  • Minimal CLS (Cumulative Layout Shift < 0.1)
  • Google PageSpeed scores 90+ for mobile and desktop

Advanced Caching Strategies

  • Redis and Memcached implementation for sub-millisecond data access
  • Varnish Cache deployment for full-page caching and reverse proxy
  • HTTP caching headers optimization (ETag, Cache-Control, expires)
  • Browser caching strategies for static assets and dynamic content

CDN & Content Delivery

  • Cloudflare, CloudFront, Fastly configuration and optimization
  • Edge computing for dynamic content at the edge
  • Image optimization with WebP/AVIF, responsive images, lazy loading
  • Asset bundling and compression (Gzip, Brotli)

Database Optimization

  • Query optimization and indexing strategies for PostgreSQL, MySQL, MongoDB
  • Connection pooling (PgBouncer, ProxySQL) for reduced latency
  • Read replicas and sharding for horizontal scalability
  • Slow query analysis and execution plan optimization

Frontend Optimization

  • Code splitting and tree shaking with Webpack, Vite, Rollup
  • Critical CSS extraction and inline styles
  • JavaScript optimization: async/defer loading, prefetch/preload
  • Resource hints (dns-prefetch, preconnect) for third-party services

Performance Monitoring

  • APM tools: New Relic, Datadog, OpenTelemetry integration
  • Real User Monitoring (RUM) for actual user experience metrics
  • Synthetic monitoring with Lighthouse CI, WebPageTest automation
  • Performance budgets and automated alerting
