Hi, This project needs an Android-first shopping experience that is optimized for both conversion and a reliable 12-week launch, with Xendit and Firebase handled properly from development through production. → Build the minimalist Android storefront in Kotlin/Java, covering product browsing, cart management, vouchers, order summaries, ratings/reviews and a secure Xendit checkout with test/live modes. → Integrate Firebase push notifications for new arrivals and flash sales, with proper handling of notification permissions and deep links into relevant products. → Follow the proposed milestones: clickable UI prototype by week 2, tested APK + commented source by week 8, then Play Store-ready production build, listing assets and handover by week 12. The implementation will include proper API/payment error handling, responsive Android layouts, testing across devices, and a clean codebase that remains easy to maintain after launch.

The app can support a 30% sales target through fast browsing, reliable checkout, and timely promotions, but the result must be measured rather than guaranteed by software alone. I’ve built mobile commerce and payment workflows, including product catalogues, carts, secure gateway handling, notifications, and production releases. I would use Kotlin with Jetpack Compose, MVVM, Coroutines, Room, Retrofit, and Firebase Cloud Messaging for a maintainable Android build. Xendit payments will be created and verified through the backend, with webhook-driven order status updates rather than trusting the device response. The cart will support quantity changes, vouchers, totals, failed-payment recovery, and order confirmation. Reviews will include authenticated purchase checks where supported, while notification topics will separate new arrivals from flash sales. I’ll also add analytics for product views, cart additions, checkout starts, purchases, and voucher use so sales performance can be measured after launch. Does an existing backend/admin system already manage products, stock, orders, vouchers, reviews, and Xendit webhooks?

@GobindSawarn

Hello, I’d love to help build your Android shopping app with a clean, minimalist experience focused on making browsing and checkout fast and effortless. I understand your three-month deadline and milestone-based delivery, and I can work within your Rp 50,000,000 budget. Tech Stack & Features Kotlin + Android: Native Android application Xendit: Secure payment integration with test/live modes Product catalog, details, ratings & written reviews Cart with quantity updates, vouchers and order summaries Firebase Cloud Messaging: New-arrival and flash-sale notifications Secure API integration and responsive UI Google Play production release under your account Timeline Phase 1: UI prototype & architecture — Week 1–2 Phase 2: Core app, cart, checkout & Xendit — Week 3–8 Phase 3: Testing, optimization, Play Store & handover — Week 9–12 I'll provide clean, maintainable Kotlin code, commented commits, thorough testing, production APK/AAB, Play Store assets, and a short handover video. I’ll also structure analytics and conversion tracking so you can measure sales, checkout behavior, and campaign performance after launch. Please share your product data, branding assets, and whether the backend/API already exists. I can then confirm the implementation plan and start with the Week-2 prototype. Best regards, Govind

Hi, I’ve built Android commerce apps where the tricky part is keeping the whole purchase flow reliable, especially around payment callbacks, order states, and push notifications. Xendit and Firebase are both straightforward to work with, but I’d make the payment flow and backend verification the priority rather than trusting the client-side result. One thing I’d confirm first is whether you already have an existing backend/API for products and orders, or if the app should include the backend as well? I’d start with the clickable UI and get the core shopping journey approved early. From there I’d build the catalog, cart, vouchers, reviews, checkout, Xendit integration, and Firebase notifications, testing both payment success and failure cases. I’d then prepare the production build and handle the Play Store submission under your account. Happy to work around the three milestone schedule. Abel

@unstopablevikas

I can build and deliver your Android shopping app within the 12-week timeline, including Xendit payment integration, cart/vouchers, product reviews, Firebase push notifications, testing, and Google Play deployment. I have 8+ years of mobile development experience with Android and Flutter, along with backend/API integration. I can handle the complete process from UI prototype through production release. **Timeline:** 12 weeks **Deliverables:** Prototype → Working APK/source → Production Play Store release I can start immediately and provide regular progress builds for review.

@venplura

Hi there! Three months to launch with a 30% sales lift target means you need speed without cutting corners on checkout security or user experience. I've built several Android commerce apps using Kotlin and Firebase, with particular focus on payment gateway integration and push notification flows that actually drive repeat visits. One thing I'd flag: the minimalist design direction is smart for conversion, but product discovery and filtering matter just as much as the checkout itself. Depending on your catalog size and customer browsing patterns, a thoughtful search and category structure will probably have more impact on that 30% goal than anything else in the scope. Before we dig into the details, it'd help to know whether you're planning inventory sync from an existing backend system, or if I'll be managing product data through a simple admin panel. That'll shape how we structure the architecture and timeline. Happy to walk through the approach and milestone breakdown if this feels like a fit. kind regards, Corné

@David198493

The main challenge with an Android e-commerce app is not only building the shopping screens, but creating a reliable buying experience where product discovery, checkout, payments, notifications, and order handling work smoothly from the first release. A 30% sales growth target also depends heavily on conversion-focused UX, app performance, and retention features rather than only technical implementation. Do you already have an existing website/backend that the app should connect to, or should the first version include a complete commerce backend? I’d approach this by designing a lightweight, scalable Android commerce platform with a clean minimalist interface, secure payment integration, and a foundation that can support future growth. I have experience building mobile applications, e-commerce platforms, payment integrations, API-driven systems, authentication workflows, and production deployments. My focus is delivering maintainable applications with clean code, reliable functionality, and a smooth user experience. I understand your three milestone structure and can work toward the week 2 prototype, week 8 functional APK/source delivery, and week 12 production launch timeline with proper testing at each stage. I’d be glad to review your product catalog, branding materials, and current business workflow to define the most efficient Android app architecture.

You need a clean Android store that reaches the Play Store in 6 weeks, with Xendit checkout, cart and voucher flows, reviews, and Firebase-driven promotion alerts. My closest match is mobile commerce work with React Native, payment webhook flows, and production release delivery; for your required source format, I can build the Android app in Kotlin. I’ll deliver the approved clickable prototype by week 2, then build the catalogue, cart, Xendit test/live payment flow, reviews, push notifications, and order states with structured, commented commits. I’ll test payment success/failure cases, APK builds, Android device layouts, and Play Console release requirements before handover. I’ll also add analytics events around product views, checkout, and purchase so you can measure the sales target accurately. The app can support a 30% sales-growth goal, but that result also depends on traffic, pricing, inventory, and promotions. Do you already have a product/order API and active Xendit merchant account?
