I want to bring a fresh Android-only mobile app from concept to Google Play release. The exact domain is still flexible—e-commerce, social networking, productivity, or another category that makes strategic sense—so I’m looking for a developer who can help me shape the idea as well as code it. Here’s what I need from you: • Discovery & wireframing sessions to refine the core feature set • Clean, maintainable Kotlin or Java code that follows Android best practices • A modern UI built with Material Design components • Integration of essential services such as authentication, push notifications, analytics, and in-app purchases when relevant • End-to-end testing, including unit tests and UI tests, with clear test reports • Assistance with Play Store listing, signing, and rollout Acceptance criteria: 1. The app installs and runs smoothly on current Android versions (API 24+). 2. All agreed-upon features are fully implemented and documented. 3. Source code builds without errors in Android Studio and is handed over in a private Git repository. 4. Play Store submission assets (icons, screenshots, copy) are complete and approved. If this sounds like a challenge you’re excited to tackle, let’s discuss timelines and milestones so we can get started right away.
