Project Nexus was a challenging initiative to replace an outdated, slow data monitoring system with a modern, high-performance dashboard capable of displaying thousands of real-time data points without lag. The core goal was to reduce cognitive load for analysts and improve decision-making speed.
The legacy system suffered from poor data visualization, requiring users to manually cross-reference figures across multiple screens. Through structured interviews, we found users spent 40% of their time simply locating the necessary data, not analyzing it.
We designed a system based on modular widgets, allowing users to customize their view for specific tasks. Leveraging **React Hooks** and a streamlined **Redux Toolkit** store, we achieved sub-50ms data updates, significantly exceeding performance benchmarks. Data visualization was handled using D3.js integrated directly into React components.
Nexus successfully launched to the internal team and led to a company-wide adoption rate of 95% within the first month. The improved data access directly correlated with a 15% measured reduction in major operational errors.
