Product designer and hands-on builder focused on AI-native interaction. I designed and built Deejiar, an AI travel planner, from concept to App Store. My work turns model output into trustworthy product behavior: validating stops against real opening hours, computing routes, and letting people adapt an entire journey with one tap instead of writing another prompt.
