I urgently need a seasoned Android engineer to take a brand-new idea from concept through to a fully working application. The exact feature set is still open for discussion, but whatever we build must run smoothly on both the latest devices and older phones and tablets without breaking UI or functionality. You will handle architecture, coding, testing, and deployment to Google Play, providing me with the full source code and a signed APK at each milestone so I can track progress. Expect to optimise for performance, follow modern Material guidelines, and implement solid backward-compatibility strategies—whether that means leveraging AndroidX, shrinking the APK with ProGuard/R8, or tailoring layouts with resource qualifiers. Clear, well-commented Kotlin or Java, Git-based version control, and concise setup documentation are part of the hand-off. I’m ready to move quickly, so please tell me how soon you can start and share a brief outline of your development approach.

Hello! I can take your Android app from concept to a fully working, Play Store–ready product, handling architecture, development, testing, and deployment end to end. I’m comfortable starting with an open feature set and shaping it into a stable, scalable build that performs well on both latest devices and older phones/tablets. How I’ll approach this 1. Architecture & Planning • Define core flows and technical scope quickly • Clean architecture (MVVM), AndroidX-first • Backward compatibility strategy from day one 2. Development & Performance • Kotlin (or Java if preferred), well-commented code • Material Design–compliant UI • Responsive layouts using resource qualifiers • APK size and performance optimisation (R8/ProGuard) 3. Testing & Deployment • Regular milestone builds with signed APKs • Device and OS-level testing • Google Play–ready configuration and deployment 4. Handover • Full source code in Git • Signed APK at each milestone • Concise setup and build documentation I’ve built and shipped Android apps that required strong performance, compatibility across OS versions, and clean maintainable codebases. I can start immediately and move fast with clear checkpoints. Happy to discuss your idea, timeline, and priorities so we can lock the scope and begin right away. Best regards, Jasmin

Hi — I can take this Android idea from concept to Play Store with attention to AndroidX, ProGuard/R8 shrinking, Material guidelines, and backward compatibility for phones and tablets. - I will produce Git-based commits and provide signed APKs + full source at milestones; I can share links to past Android projects and code samples on request. - I work with Kotlin or Java and will apply AndroidX, resource qualifiers, and APK shrinking strategies as required. - I’ll supply concise setup docs and well-commented code so you can build and run locally. Plan - Approach: quick discovery (features, target devices, minSdk), architecture (modular + DI), then iterative sprints with a working APK each sprint. - Milestones: PoC (UI/critical flows) → MVP (core features, tablet/phone support) → Final (polish, play store submission). Signed APK & repo at each milestone. - Quality & testing: device/family matrix, unit + instrumentation tests, lint, performance profiling, and CI builds. Two quick questions to start 1) What are the 2–3 must-have features for MVP? 2) What minimum Android API level and specific older devices you must support? Ready to start within 48 hours. Message me and we’ll lock scope and first milestone — you can check my reviews on my profile.
