Hi, I'm Arungi Cahaya

I'm a software engineer with more than 5 years of experience, currently working at Flip as a software engineer, and based in Jakarta, Indonesia.

As a generalist software engineer, I have strong experience across the stack, with a primary focus on mobile development, especially React Native and native Android (Kotlin), as well as building and integrating backend services and APIs.

I enjoy working end-to-end on products, from designing user experiences to implementing reliable backend logic. Even when challenges arise, I stay focused on problem-solving and delivering practical, well-engineered solutions.
