I am developing my portfolio through hands-on experiments: mobile learning products, AI assistant prototypes, web interfaces, and visual showcases. My goal is to make every project clear enough to use and polished enough to present.
Hi, I'm Jonathan Ansell Prasetya
I am a student builder and creative developer working across Flutter, Firebase, AI APIs, local tools, and visual storytelling. I like making projects that feel useful, polished, and easy to understand.
