Hi 👋, I'm Liu Purnomo
A passionate full-stack engineer with over a decade of experience crafting reliable, scalable digital products.
I specialize in building modern web and mobile applications using JavaScript, TypeScript, and frameworks like Next.js and React Native.
Driven by curiosity and care for usability, I love transforming complex ideas into elegant, human-centered solutions—and sharing what I learn along the way.
