Hi, I'm Iwan.

Mobile Application Developer from Wonogiri with 5+ years designing, building, and maintaining Android apps in Flutter/Dart — from first wireframe to live on Google Play.

20+ production apps shipped with full release ownership. Clean architecture, REST API integration, and Play Store releases — all handled end-to-end.

Cross-disciplinary by default: mobile dev, UI/UX, and enough backend to ship without blockers.
