I designed the trip planner from the ground up, starting with research and competitive analysis of travel planning tools to understand user expectations and gaps in the market. I structured the product around a calendar-based workflow that allows users to visually organize their itinerary day by day. I created wireframes, interaction flows, and visual designs for both desktop and mobile, introduced modular activity blocks for stays, activities, and commutes, and designed collaborative features that allow travelers to invite others and plan trips together.
