React Developer Needed to Fix Memory Leak
Working with Isuru was a great experience. They quickly identified the exact source of a tricky React memory leak and implemented a clean, efficient fix with proper event listener and async cleanup logic. Communication was smooth, the explanations were clear, and the work was delivered faster than I expected. The component now runs perfectly without any memory issues, even under repeated navigation and re-renders. Highly recommended for any advanced React debugging or performance optimization tasks!
