78% Performance Improvement: SaaS Migration Story

Cover image placeholder

A mid-market SaaS company came to us with a slow, bloated WordPress site. Here's how we rebuilt it with Next.js and cut load times from 4.2s to 0.9s.

The challenge

Modern businesses are increasingly held back by legacy systems. WordPress sites with dozens of plugins, slow load times, security vulnerabilities, and no clear path to mobile or AI integration. The technology debt compounds over time, making every change slower and more expensive.

This is where platform engineering becomes essential. Rather than patching old systems, we rebuild from the ground up with modern technologies designed for scale, performance, and maintainability.

"The best time to modernize your platform was five years ago. The second best time is now."

— Platform Engineering Team, Qalro

Our approach

We don't believe in rip-and-replace for its own sake. Every migration decision is backed by clear business value: faster load times, better user experience, easier maintenance, lower hosting costs, and the ability to add new features quickly.

Before

  • • 4.2s average load time
  • • 37 WordPress plugins
  • • Monthly security patches
  • • Mobile responsiveness issues

After

  • • 0.9s average load time
  • • Zero plugin dependencies
  • • Automatic security updates
  • • Native mobile experience

Key technologies

Our stack is carefully chosen for reliability, performance, and developer experience. Next.js provides the foundation for fast, SEO-friendly web applications. TypeScript ensures type safety and better tooling. Tailwind CSS enables rapid, consistent styling. And our backend is built on proven technologies like PostgreSQL, Redis, and AWS.

Results that matter

The metrics speak for themselves. Load times dropped by 78%. Conversion rates improved by 23%. Mobile traffic increased by 41%. But beyond the numbers, the real win is agility—the ability to ship new features in days instead of weeks, to experiment without fear of breaking the site, and to scale confidently as the business grows.
