I built screen systems that organised data into clear sections — maps, metrics panels, detail views — and used layout, colour, and hierarchy to steer attention to the signals that mattered. I structured flows that carry a user from an overview map into specific drill-downs, which gave the team a concrete usage narrative for demos and sales conversations. The deliberate trade-off: I designed a reusable framework rather than one-off screens, accepting slower initial delivery so the tool would stay coherent as new datasets and dashboards were added.
