Enhancing React Page Performance Using AI Agents

Unlocking New Possibilities with AI in Software Engineering

Recently, I optimized a sluggish React page using AI agents, resulting in a dramatic 76% reduction in p95 frame time. This experience was eye-opening, showcasing the incredible capabilities of AI while demonstrating how far we’ve come in software engineering.

Key Highlights:

  • AI-Driven Performance Testing: Used Cursor’s AI agent, Claude Opus 4.5, to benchmark and improve page speed under realistic conditions.
  • Optimization Strategies:
    • Removed Framer Motion animations, boosting frame time by 27%.
    • Switched to Zustand for state management, achieving an additional 14% improvement.
  • Efficient Collaboration: A structured markdown file became the central hub for baseline metrics and optimization ideas, allowing seamless agent interaction.

This experience underscores a shift toward AI-driven development, where humans can oversee instead of micromanage.
