To maintain consistency between the "Owner" and "Tenant" views, I created a robust Design System in Figma based on shared components adapted to each context. Data Visualization: I designed clean financial widgets for the owner dashboard, simplifying complex profitability metrics. IoT Integration: I prototyped the "Digital Key" functionality, ensuring the door release button was the most accessible and tactile element of the tenant interface. Incident Flows: I structured the ticketing system (chat + photographic evidence) to reduce user anxiety, using serif fonts to humanize the technical communication.
