I'm Matthew Wijaya, a Computer Science student at Universitas Indonesia working somewhere between product design, interaction, and engineering.
Selected projects involving research, interfaces, experiments, and the occasional battle with production code.
A connected sports platform across web and mobile surfaces.
A connected sports platform for discovering, booking, and reviewing facilities, coaches, and events across web and mobile.
An end-to-end HCI case study from discovery to prototype.
An end-to-end human-computer interaction project developed from real problem discovery and user interviews through information synthesis, interaction design, and a high-fidelity prototype.
A live web experience shaped through brand, flow, and responsiveness.
A live digital experience designed for PPMB KMBUI 2026, combining visual identity, information hierarchy, and responsive web execution.
A record of teams I joined, responsibilities I picked up, and things that made it out the door.
Own the UI/UX design of ppmbkmbui.net, shaping information architecture, user flows, responsive layouts, and interface consistency for freshman admissions and onboarding.
Create magazine layouts, educational Instagram content, appreciation posts, merchandise, and live-reporting assets with a consistent visual voice.
Designed social-media information assets and merchandise, photographed orientation activities, and helped communicate key incoming-student information.
Produced mascot variations, booklets, presentation decks, and social assets within an established design system, emphasizing readability and consistency.
Not everything I design becomes a product. Here’s the rest — graphics, mascots, merchandise, and visual identities.
