CONTEXT
Modernising a legacy procurement portal that had quietly broken down
Siam Commercial Bank's e-Procurement portal — the system their corporate clients used to manage invoices, purchase orders, and supplier relationships — was built for an older web era. Jargon-heavy, browser-dependent, and dense with features nobody could fully explain, it had quietly shifted work onto relationship managers who shouldn't have been doing it. Clients weren't using the tool. They were delegating around it.
Working alongside a design manager and a visual designer, I was brought in as the interaction designer to redesign the experience across five epics — mapping legacy flows, identifying friction points, and proposing a modernised interface that corporate users could actually navigate without training.
The project was cut short when Singapore closed its borders during Covid-19. All five epics were delivered and handed over to SCB's in-house development team.
