Overview
iOS engineer at a Middle level specializing in Swift and practical app features such as MVVM and networking. The strongest proven skill is modern async networking and pagination as shown by Pleny_Task/Pleny_Task/Repository/NetworkManager.swift and Pleny_Task/Pleny_Task/Views/Tabs/Posts/PostsViewModel.swift. There is limited evidence of offline sync, permission flows, performance measurement or release automation in public code.

Middle Mobile Developer
Confidence: Medium iOS Engineer
iOS engineer at a Middle level specializing in Swift and practical app features such as MVVM and networking. The strongest proven skill is modern async networking and pagination as shown by Pleny_Task/Pleny_Task/Repository/NetworkManager.swift and Pleny_Task/Pleny_Task/Views/Tabs/Posts/PostsViewModel.swift. There is limited evidence of offline sync, permission flows, performance measurement or release automation in public code.
Platform Native Mastery
3/10
Knowing the mobile platform
Basic platform-native mastery: uses Swift concurrency, @MainActor, coordinator pattern and protocol-based services but lacks explicit lifecycle/process-death handling, state restoration and structured cancellation tied to view lifecycles.
Evidence
Pleny_Task/Pleny_Task/Repository/NetworkManager.swift: async URLSession usage and NetworkingError enum
Pleny_Task/Pleny_Task/Views/Tabs/Posts/PostsViewModel.swift: @MainActor methods and async pagination calls
Pleny_Task/Pleny_Task/Login/LoginView.swift: use of coordinator pattern with SwiftUI environment object and focus/keyboard handling
Mobile UI/UX & Responsiveness
4/10
Smooth mobile experience
Solid practical UI work across UIKit and SwiftUI including compositional layouts, SwiftUI focus handling, lazy grids and pagination flows, but limited evidence of accessibility, RTL, dynamic type or adaptive UI for multiple device classes.
Evidence
SataFood/SataFood/HomeVC.swift: UICollectionViewCompositionalLayout sections and orthogonal scrolling
Pleny_Task/Pleny_Task/Login/LoginView.swift: SwiftUI form with focused fields, keyboard offset handling and fullScreenCover navigation
Pleny_Task/Pleny_Task/Views/Search/SearchView.swift: LazyVGrid, .task usage and onChange with async search
Performance & Battery
2/10
Speed and battery use
Some modern async networking and decoding are present but there are synchronous main-thread image loads and no measured performance profiling, battery-aware background work or explicit memory/jank mitigations.
Evidence
Pleny_Task/Pleny_Task/Repository/NetworkManager.swift: async/await networking and JSON decoding
StarredRepos/StarredRepos/Views/RepoCell/RepoCell.swift: loadAvatar uses Data(contentsOf:) on the main thread
SataFood/SataFood/Views/Cells/NewOffersCell.swift: image data loaded synchronously with Data(contentsOf:)
Offline & Data Sync
Working offline and syncing
Not evidenced in public code
Device Integration
2/10
Using device features
Minimal device integration: keyboard and navigation flows are handled, but there is no evidence of full permission flows, location/camera/push handling or deep link handling.
Evidence
Pleny_Task/Pleny_Task/Login/LoginView.swift: keyboard handling, focused fields and fullScreenCover navigation
Pleny_Task/Pleny_Task/Helpers/KeyboardHandler.swift: keyboard height listener (helper referenced by views)
Release & App Lifecycle
2/10
Building and publishing apps
Basic test artifacts exist including unit and UI tests, but there is no evidence of CI/CD, release automation, crash reporting integration or signing/release provisioning.
Evidence
StarredRepos/StarredReposUITests/StarredReposUITests.swift: UI test scaffolding and launch performance test
SataFood/SataFoodUITests/SataFoodUITests.swift: UI test scaffolding and launch performance test

Recommendations
- Build networked iOS features and API-driven screens that need async/await, pagination and coordinator-based navigation.
- Implement performant image loading and caching (move off main thread, use URLCache or a lightweight caching layer) to improve UX on list screens.
- Expand testing into unit tests for view models and add CI pipelines or TestFlight release automation to support releases.
- Add offline-first support or local persistence (Core Data or lightweight store) and design idempotent retry/sync logic for background network work.
