Short Description
This article concerns how we handled performance optimization on our enterprise-scale eCommerce platform, built with Next.js and deployed on Vercel. We went from sluggish load times, unstable layouts, and red Core Web Vitals to a perfect Speed Insights score, improving from around 60 to consistently above 95.
Along the way, we rethought our rendering strategy, reduced JavaScript bloat, restructured our API layer, and set up continuous performance checks. The payoff was huge: faster pages, better rankings, and higher conversions, all while serving over 12 million visitors every month. I’ll walk through the technical details, including rendering strategy, caching, minimizing JavaScript, and monitoring performance continuously.
