Adi Wiratama Banjarnahor is an Indonesian interdisciplinary designer bridging physical spaces, digital products, and strategic execution. By combining training in architecture, urban design, interaction design, and business logic, I help tech and commerce companies build products that solve complex human challenges.

My work moves from ethnographic spatial research to high fidelity digital prototyping. Instead of just designing screens, I map complex physical ecosystems, test for product viability, and engineer interactive tools that are structurally sound and deeply human.

Discovery & Ethnography

I start by getting close to the problem, observing, mapping behavior, and finding where a system actually breaks down for the people inside it.

Service Architecture & Strategy

I translate research into direction, a clear position on what to build, who it serves, and why it will hold up commercially.

Prototyping & Usability Testing

I turn strategy into something tangible, journeys and prototypes, then test early and often, refining against real behavior until it’s ready to scale.
