I want to create a simple mobile application dedicated to one thing: berbelanja. My parents do all of their shopping on an aplikasi mobile, so the entire experience must feel effortless on a phone—from the first splash screen to a completed checkout. The single feature they value above everything else is an akurat, lightning-fast pencarian produk. Type a name or scan a barcode, see results instantly, filter them, and tap to buy. If a shopper can’t find an item in two or three seconds, the feature has failed, so performance matters as much as design. Here’s what I need delivered: • A production-ready Android APK (iOS later is optional but not required for this milestone). • Source code with clear README explaining how to build and maintain it. • A short walkthrough video or live demo link proving that product search works quickly on real data and the purchase flow completes without errors. If you have experience integrating secure mobile payments and building high-performance search in Flutter, React Native, or native Android, let’s talk—my goal is to get this into my parents’ hands as soon as possible.
