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.
