I started with task flows and mindmaps in FigJam so everyone could see the logic before anything got drawn, then moved through low fidelity wireframes with the client in the room at each step. That collaboration is why the high fidelity screens needed so few revisions later. The final UI covers the browse and filter experience, the pack builder, cart, checkout, payment and order confirmation, all built on the existing
Snacks.com colour and component language so it shipped as one continuous product rather than a bolt-on.
