AI builds tools that ship your SaaS fast, then quietly leave it failing Core Web Vitals. I rebuild React & Next.js apps to achieve Lighthouse 90+, cut load times by up to 40%, and restore the search rankings that bloat is costing you. The AI Performance Paradox: code from Cursor, v0, or Copilot runs, but it ships with oversized bundles, layout shift, and main-thread blocks that wreck LCP, INP, and CLS. I audit that code and fix it at the architecture level, not with vanity tricks. Real outcomes I've delivered: 1. Rendering at scale — re-architected a simulation dashboard handling 7,000+ visual entities from severe lag to a smooth 60FPS with LCP under 2.5s. 2. Mobile Core Web Vitals — eliminated main-thread bottlenecks on a high-volume agritech SaaS, holding Lighthouse 90+ even under heavy data rendering. 3. Speed that cuts cost — optimized Node.js/Python pipelines to drop server infrastructure costs 4. 40% while keeping enterprise-grade stability. I optimize against real Google CrUX field data — what your actual users experience — not cached lab scores that look great and change nothing. If you've been burned by a "99 PageSpeed" that never moved your traffic, that's exactly the gap I close. Backed by a 100% Job Success, Top Rated record across 12 projects — "Outstanding experience! Highly recommended!" Want to know what's slowing you down?
