You will get React / Node.js Performance Optimization & Speed Fix Expert

Project details
I specialize in diagnosing and fixing real-world performance issues in React and Node.js applications, focusing on measurable speed gains, not cosmetic changes. I combine deep frontend profiling with backend optimization to improve API response times, database efficiency, and UI rendering performance. Every optimization is data-driven, validated under load, and aligned with scalable architecture practices. The goal is simple: faster applications, lower resource usage, and a smoother user experience that holds up under real traffic.
