TerminalOne is a digital petroleum marketplace that simplifies how AGO and PMS are bought, sold, and managed at scale. I led the end-to-end product design—starting with user flow definition and stakeholder workshops to ensure clarity in the complex B2B trading process. The goal was to create an experience that felt powerful yet approachable; guiding both buyers and suppliers through product listings, contract signings, and last-mile logistics without friction. I designed the features page to break down technical offerings into digestible, benefit-driven sections, paired with a clean, responsive interface that works seamlessly across devices. From secure supplier onboarding to real-time co-loading support, every interaction was thoughtfully designed to build trust, drive action, and reflect TerminalOne’s role as a next-gen trading platform for energy in Africa.
