I’m ready to turn my e-commerce concept into a fully-functional Android application. The core flow is standard: browse catalog, add items to cart, check out securely, then review past orders. Account creation and sign-in must rely on email + password credentials, with password reset handled in-app. Alongside the shopping flow, I also want a lightweight task-management panel. Think of it as a to-do list where users (or internal staff) can create, mark complete, and reorder tasks related to their purchases—nothing heavy, but it should feel native and sync to the same backend as the store data. Key deliverables • Android app built in Kotlin (Java is acceptable if you have strong reasons) • Product listing, search/filter, cart, checkout, order history • Ema...

I’m embarking on an ambitious project to launch a pair of operating systems — one for mobile devices and one for desktop / laptop computers. I deliberately chose Both platforms because I need a seamless experience across phones, tablets, and traditional PCs, without depending on Android, iOS, Windows, macOS, or any other pre-existing stack.

I’m taking my neighbourhood kirana shop online and need a compact e-commerce site that feels effortless on any phone. The core of the job is a modern, clean design that loads fast and makes ordering as simple as walking to the counter.
