Firestore & Realtime Database: Real-time sync, offline persistence, security rules. Analytics, Crashlytics & Remote Config: Event tracking, crash reporting, A/B testing. Monetization & Location Google Play Billing & Subscriptions: In-app purchases, tier management, server validation. Google Maps & Location: Custom markers, clustering, geofencing, offline caching. Security & Encryption Android Keystore & BiometricPrompt: Hardware-backed keys, biometric gating. Certificate Pinning & Network Security Config: HTTPS enforcement, cleartext blocking, pin rollover. Runtime Protection: Root/emulator detection, APK signature checks, basic anti-debugging, ProGuard/R8 obfuscation. Background & Automation AccessibilityService & USSD Automation: Read/interact with USSD dialogs, multi-SIM support, non-blocking state machines. WorkManager & Foreground Services: Reliable background tasks that survive restarts and system limits. UI/UX & Performance Animations & Transitions: AnimatedVisibility, MotionLayout, Material motion guidelines. Responsive Layouts & Internationalization: Support all screen sizes, RTL for Arabic/French/English, proper pluralization. Memory & Battery Efficiency: Leak detection (LeakCanary), profiling (Android Profiler), RecyclerView/LazyColumn optimization. Ads & Engagement AdMob, Facebook, Unity, IronSource, etc.: Banners, interstitials, rewarded and native ads with minimal overhead, frequency capping, test-device setup.

CI/CD (GitHub Actions, GitLab CI, Fastlane): Automated builds, tests, vulnerability scans (OWASP Dependency-Check), signed AAB deployment to Play Store. Why Work With Me? I apply a “security-first” mindset from design (threat modeling, encryption, pinning) to production, proactively fixing vulnerabilities. My data-driven approach—analyzing crash reports, analytics, and user feedback—delivers stable, secure features quickly. I also mentor junior developers on best practices (Kotlin Coroutines, DI, Jetpack Security) and continuously refine workflows (migrating to Compose, exploring Kotlin Multiplatform). Whether you need a security audit, performance tuning, or end-to-end feature development (from Firebase backend to polished UI/UX), I’m ready to deliver robust, user-safe Android apps.
