Project description:
"I need a full-stack developer to take an Android e-commerce idea from concept to a polished, production-ready release. The app will let users browse, select, and purchase on-demand services rather than physical goods, so smooth scheduling logic, dynamic pricing, and a streamlined checkout flow are essential.

Core scope
• Design the UI/UX for an intuitive service marketplace.
• Build the Android front end (Kotlin or Java—your call, as long as it follows modern MVVM or MVI patterns).
• Develop the back end and API layer to handle user accounts, service listings, cart, orders, reviews, and push notifications. Firestore, PostgreSQL, or a similar scalable store works; I’m open to your recommendation.
• Integrate a secure payment gateway. I haven’t locked in a provider yet, so advise on the best option and wire it into the checkout flow.
• Set up basic admin tools so I can add, edit, or remove services without touching code.

Deliverables
1. Full Android source code in a private repo, clearly documented.
2. Deployed back-end (cloud or on-prem) with environment scripts.
3. One signed release APK plus a debug build for future iterations.
4. A short hand-off guide covering build, deploy, and maintenance steps.

Acceptance criteria
• Users can register, log in, browse services, add to cart, check out, and view order history without crashes or major UI glitches.
• Payments process successfully in sandbox and live modes.
• All network calls respond in <2 s on a 4G connection.
• Code passes a quick review for clean architecture and lint compliance.

If you have prior examples of service-based commerce apps, link them along with a rough timeline for each milestone so we can move forward quickly." (client-provided description)
