About

I'm an XR Engineer and game developer based in Kuala Lumpur, currently working on User Experience Design and Active Learning at APU's Centre of Excellence for Extended Reality Technology & AI. My work sits at the intersection of Unity development, interactive and UI/UX design, immersive research, and teaching. I've spent the last three years managing a university XR studio, mentoring student developers, and building VR systems and games people actually learn from and enjoy using.

My MSc research explored a hybrid metaverse framework for gamified virtual campus tours, combining Meta Quest deployment, AI-powered conversational NPCs, and multiplayer networking into one coherent system. That same instinct for combining disciplines runs through my project work: game design and development, cultural heritage preservation, sports science, insurance training, UI/UX flows, and bilingual science education, often with original visual and graphic design work of my own.

I'm currently exploring roles across XR/game engineering, VR development, UI/UX and interactive design, graphic design, and university lecturing in immersive technology.
