Frontend performance directly impacts user experience, engagement, and SEO — yet many bottlenecks go unnoticed until they start slowing everything down. I just published a complete guide that breaks down the most common performance issues developers face and how to fix them with practical, real-world strategies.
⚡ What the guide covers
- JavaScript bundle bloat (and how to reduce it)
- Inefficient CSS and layout thrashing
- Image-related performance issues
- Slow API responses and rendering delays
- Poor caching and unnecessary reflows
- Web Vitals metrics that actually matter in 2025
- Tools to measure and fix performance problems
If you're building modern web apps and want them to load fast and run smoothly, this guide will help you systematically identify and eliminate bottlenecks.
