I can help you drastically improve the speed and responsiveness of your Node + React application by diving straight into the backend bottlenecks. With experience in Express, JWT middleware, and integrating third-party APIs, I focus on profiling, optimizing, and benchmarking Node services to ensure measurable performance gains under real-world load. I’ve previously delivered similar optimizations where response times dropped by 30–50%, with no impact on stability. I can start immediately and focus on results you can measure and trust. Would you like me to prepare a quick initial audit of your Node services to pinpoint the biggest wins before we proceed?
