IDSS Engine is a decision support platform developed at NOAA's Global Systems Laboratory to help National Weather Service forecasters proactively communicate weather hazard risk to emergency managers and partner agencies across the country. The tool enables forecasters to build criteria-based monitoring profiles, automatically assess incoming weather data against user-defined thresholds, and generate timely impact-based notifications — reducing the cognitive burden of continuous manual monitoring across 120+ Weather Forecast Offices nationwide. As the lead UX designer and de facto product manager on the project, I owned the end-to-end design of the interface while managing the engineering and design backlog, facilitating standups, and coordinating cross-functional efforts with MDL's development team toward a full national release targeted for September 2026.
