When the Indonesia Stock Exchange needed a gallery installation regular people wouldn't bounce off, I designed the interface that kept them tapping.

In 2018, the Indonesia Stock Exchange wanted a permanent gallery installation that could make stock trading approachable to everyday visitors, students, first-time investors, walk-in traffic, not just finance professionals. This was also before screen-prototyping tools were standard, which meant validating interactions took real legwork.

As lead interface designer working with Sembilan Matahari, design the interface layout, typography, 3D asset placement, and interaction flows for a touch-friendly, gallery-ready installation, and prove the experience would work before it was physically built.

• Engineered a dynamic, touch-friendly UI with real-time feedback loops, pairing clear financial typography with expressive 3D compositions from the studio's 3D artists.
• Ran a full design sprint process, since off-the-shelf prototyping tools weren't yet reliable for this kind of physical-digital installation.
• Produced full-scale video motion simulations to preview timing, screen transitions, and sensor trigger states, letting the engineering team validate interactions before anything was installed on site.

The Numbers

Interface design here meant more than screens. The real job was making a genuinely intimidating topic feel like something you could walk up and try, a UX problem before it was ever a visual one.
