Overview
Cross-platform Flutter developer (middle level) focused on building feature-complete mobile UIs and client-side app logic. Proven strength is implementing end-to-end Flutter UI and client state flows as shown by Online-Shop/lib/Screen/auth_screen.dart and Online-Shop/lib/provider/auth_provider.dart together with widget-heavy screens in the Fitness-Assessment app. There is little to no public evidence of background sync engines, advanced native platform integrations, permission denial handling, CI/CD pipelines or performance profiling results.

Full-Time
Built and maintained a Kotlin Multiplatform codebase for a large-scale learning product, including shared UI and business logic. Developed Android-native features with Jetpack Compose plus local storage using DataStore and Room/SQLDelight, and added analytics events. Implemented interactive learning experiences including a lifecycle-aware video player and real-time virtual classroom streaming, and improved build/testing workflows with custom Gradle variants. Delivered study material and engagement features using WebSockets and animations.

Middle Mobile Developer
Confidence: Medium Cross-platform
Cross-platform Flutter developer (middle level) focused on building feature-complete mobile UIs and client-side app logic. Proven strength is implementing end-to-end Flutter UI and client state flows as shown by Online-Shop/lib/Screen/auth_screen.dart and Online-Shop/lib/provider/auth_provider.dart together with widget-heavy screens in the Fitness-Assessment app. There is little to no public evidence of background sync engines, advanced native platform integrations, permission denial handling, CI/CD pipelines or performance profiling results.
Platform Native Mastery
2/10
Knowing the mobile platform
Limited native platform lifecycle handling is present via persisted auth and widget lifecycle management, but there is no deep native code, process-death handling, or platform-specific lifecycle work.
Evidence
Online-Shop/lib/provider/auth_provider.dart: tryAutoLogin, logout and refreshToken using SharedPreferences and a Timer for token expiry
Online-Shop/lib/Screen/auth_screen.dart: _AuthCardState initState/dispose managing AnimationController
Online-Shop/lib/Screen/edit_product_screens.dart: initState/didChangeDependencies/dispose with FocusNode management
Mobile UI/UX & Responsiveness
4/10
Smooth mobile experience
Solid, practical Flutter UI work with responsive sizing, animations and common UX patterns, but mostly page-level implementations rather than advanced adaptive or accessibility engineering.
Evidence
Online-Shop/lib/Screen/auth_screen.dart: responsive layout using MediaQuery, AnimatedContainer, SlideTransition and FadeTransition
Fitness-Assessment/lib/Screens/HomeScreen.dart: responsive layouts with MediaQuery, AdvancedSegment control and Firebase-driven UI
Online-Shop/lib/widgets/product_Item.dart: Hero, FadeInImage and SnackBar usage for smooth UX
Performance & Battery
2/10
Speed and battery use
Some attention to rendering and UX (placeholders, image caching hooks) but no measurement-driven performance work, profiling, or battery-aware background optimizations.
Evidence
Fitness-Assessment/lib/Components/CacheImages.dart: custom CachedImage usage across screens
pubspec.yaml files: cached_network_image dependency in Fitness-Assessment and use of FadeInImage in Online-Shop widgets
Offline & Data Sync
2/10
Working offline and syncing
Basic offline persistence and remote data fetch patterns are present (SharedPreferences for auth, Firebase realtime usage), but there is no explicit sync engine, conflict resolution, or queued idempotent retry logic.
Evidence
Online-Shop/lib/provider/auth_provider.dart: stores auth token/userData in SharedPreferences and implements refreshToken
Online-Shop/lib/provider/products_provider.dart: fetchandset, addProduct and UpdateProducts interacting with Firebase REST endpoints
Fitness-Assessment/lib/Components/AssessmentList.dart: FirebaseAnimatedList streaming data from Firebase Realtime Database
Device Integration
1/10
Using device features
Uses cloud and media APIs (Firebase, network images) but lacks full device-integration flows like permission handling, camera capture flows, geolocation or push notification handling with denial paths.
Evidence
Fitness-Assessment/pubspec.yaml: firebase_core and firebase_database dependencies present
Fitness-Assessment/lib/Screens/HomeScreen.dart: FirebaseDatabase.instance usage and FutureBuilder/StreamBuilder patterns
Release & App Lifecycle
1/10
Building and publishing apps
No evidence of release engineering, CI, store configuration, staged rollouts or crash-report triage in human-authored code; build files appear standard project boilerplate.
Evidence
android/build.gradle files present in projects - standard Flutter project configuration
pubspec.yaml files defining versions and dependencies but no CI/CD or fastlane configuration

Recommendations
- Build medium-sized Flutter features that need solid UI, form handling and Firebase integration such as user auth, product CRUD and realtime lists.
- Implement offline-capable sync or work-queue features that require idempotent retries and conflict resolution to grow into a senior mobile role.
- Add measured performance work - instrument screens, track jank and memory, and iterate with targeted fixes.
- Own end-to-end release tasks like CI/CD, crash reporting and proguard/R8 configuration to demonstrate release engineering experience.
