Hi! I’m a product designer and UX researcher with a design engineer background from Hanyang University and an Apple Developer Academy alumna. Over the past years I have loved turning complicated problem into experiences that feel simple and human, from my time at a laboratory to my current role as Senior Product Designer at PT Rpay Financial Indonesia, where I lead design strategy and builds design systems.

My expertise spans UX research, UI/UX design, design systems, and a little front-end development, blending creativity with technical skills so I can talk comfortably with designers and engineers alike. I cares deeply about accessibility, which is why I joined A11YID as UX research volunteer and designed FIMO Kids, an iOS app for children with dysgraphia. I also spend my free time at Hamari Studio as my creative projects, where most of the projects were helping small businesses bring their ideas to life, and I thrives on collaboration. Outside of work, she enjoys exploring cultures, writing, drawing, and doing research.

💻 As Product Designer


As a product designer, I am dedicated to developing solutions that balance user needs with business goals. I excel at conducting user research, designing wireframes and prototypes, and collaborating with developers to turn concepts into reality.

My design philosophy centres on universal design. It is shaped by growing up as a nomad, which exposed me to diversity and taught me that technology should be accessible and inclusive for everyone, regardless of background or ability. By combining strategic thinking with empathy, I strive to create meaningful, impactful experiences that resonate with diverse audiences.
