SCROLL TO WORK↓I’m a product-minded software developer based in Kuala Lumpur. I work where engineering, interaction, and systems thinking meet—building interfaces that remain clear even when the product underneath is complex.
My best work happens with ambitious teams who care about the details: how information moves, how feedback feels, and how a product earns trust over time.
