The Core Principles

In our experience building dozens of high-performance applications, we've found that performance isn't something you can sprinkle on at the end. It's a fundamental architectural decision.

Key Takeaways

  • Always prioritize server-side rendering for critical data.
  • Optimize images and assets using modern compression.
  • Use GSAP for performance-safe animations that don't jank.

We believe that the future of the web belongs to those who prioritize the user's experience across all devices and connection speeds.
