Overview
A mobile iOS developer at an early-mid (middle) level who writes UIKit-based screens and view-controller-driven features. The strongest proven skill is practical UIKit development for list/grid flows and custom collection view behavior, demonstrated in TimeViewController.swift and DateViewController.swift. The codebase lacks evidence of production-grade concerns such as robust error handling, offline sync/migrations, background work, CI/release tooling or accessibility and permission flows.

Full-Time
Built and launched in production an automation platform for a table-tennis hall network, including online booking, payment, access control, live score and replay features, and IoT device control. Designed a distributed architecture with a central server and edge servers per table, implemented equipment integrations via MQTT, and developed a FastAPI-based REST API with booking, pricing, promo codes, sessions, documents, incidents, and equipment management. Developed a React PWA client and a full admin CRUD panel, implemented backend integrations and tests, and set up production infrastructure with Docker Compose, Nginx, Ubuntu Server components and monitoring dashboards.

Developed and maintained software for security systems and information technologies, including the Jupiter operator workstation using Java and JavaFX. Optimized application memory consumption from several gigabytes to stable under 2 GB, enabling stable monthly operation without restarts, and delivered multiple UI/UX improvements. Implemented automatic update/version checking, obtained a patent for the Jupiter workstation program, and rewrote mobile applications using Swift and Kotlin for iOS/Android.

Middle Mobile Developer
Confidence: Medium iOS Engineer
A mobile iOS developer at an early-mid (middle) level who writes UIKit-based screens and view-controller-driven features. The strongest proven skill is practical UIKit development for list/grid flows and custom collection view behavior, demonstrated in TimeViewController.swift and DateViewController.swift. The codebase lacks evidence of production-grade concerns such as robust error handling, offline sync/migrations, background work, CI/release tooling or accessibility and permission flows.
Platform Native Mastery
2/10
Knowing the mobile platform
Basic platform lifecycle usage is present (AppDelegate / SceneDelegate and view controller lifecycle methods) but there is no evidence of state restoration, process-death handling, structured concurrency or cancellation tied to screen lifecycle.
Evidence
Delushon/CyberAction/CyberAction/Application/AppDelegate.swift: application(_:didFinishLaunchingWithOptions:), configurationForConnecting and persistentContainer
Delushon/CyberAction/CyberAction/Application/SceneDelegate.swift: scene(_:willConnectTo:options:) and other scene lifecycle stubs
Delushon/CyberAction/CyberAction/Controllers/BookingViewController.swift: viewDidLoad / viewWillAppear usage
Mobile UI/UX & Responsiveness
2/10
Smooth mobile experience
UI code shows practical UIKit skills - collection views, custom cell sizing and manual snapping logic - but no evidence of adaptive layouts, accessibility, dynamic type, RTL support or measured jank fixes.
Evidence
Delushon/CyberAction/CyberAction/Controllers/TimeViewController.swift: custom horizontal UICollectionView, cell sizing and scrollViewWillEndDragging snapping logic
Delushon/CyberAction/CyberAction/Controllers/DateViewController.swift: programmatic month grid construction in setup(cell:month:)
Delushon/CyberAction/CyberAction/Controllers/BookingViewController.swift: collectionView cell sizing and registration
Performance & Battery
1/10
Speed and battery use
Minor performance awareness (cell reuse and nib registration) is present, but there are no performance measurements, profiling artifacts, memory-leak fixes or doze-aware/background battery considerations.
Offline & Data Sync
1/10
Working offline and syncing
A Core Data stack exists indicating awareness of a local store, but there is no migration history, sync engine, queued offline operations or network conflict-resolution logic.

Not evidenced in public code

Recommendations
- Replace fatalError/force-unwraps with safe error handling and add Core Data migration handling and graceful failure paths in AppDelegate.saveContext / persistentContainer.
- Add unit/UI tests and small performance measurements (time-to-first-draw, cell render time) and profile collection view performance to remove potential jank.
- Implement offline-first patterns or a simple sync queue and idempotent retry for bookings, and add migration/versioning for local data.
- Improve accessibility and adaptive UI: support dynamic type, test on varied device sizes (iPad/compact) and add localization/RTL checks.
Repositories
The developer's experience in this domain has been verified based on AI analysis of the following repositories:
Junior Frontend Developer
Confidence: Low App Engineer
A junior-level frontend developer who produces small, DOM-driven UIs and simple Node-served SPAs. The strongest proven skill is client-side UI construction and data rendering, evidenced by Delushon/website/app.js addPersonToCollection and Delushon/spa-node/index.html buildTableTop/buildTableAll. The public code does not show component architecture, responsive design, accessibility best practices, automated tests, or advanced state management patterns.
UI Component Architecture
2/10
How interface parts are built
Monolithic DOM-manipulation approach with no component boundaries, composition, or reuse patterns.
Responsive & Cross-browser
1/10
Works on all screens and browsers
Layout uses fixed pixel widths and no responsive strategies; Bootstrap is included in another page but not leveraged for a responsive architecture.
Performance Optimization
1/10
Speed of the interface
No measured performance work or code-splitting; client-side loops repeatedly parse JSON which is inefficient but small scale.
Accessibility & Semantics
1/10
Usable for everyone
Minimal accessibility consideration - missing labels/ARIA and semantic roles on interactive controls.
State Management & Data Flow
2/10
Managing data in the app
Simple global state usage and client-side rendering - basic data flows exist but no cancellation, optimistic updates, or structured state management.
UX & Visual Polish
2/10
Look and feel quality
Basic UX flows implemented (show/hide registration/auth screens, styled cards) but missing loading/error/empty states and undo patterns.

Recommendations
- Assign to build or maintain small static sites and simple SPA pages where direct DOM manipulation is acceptable.
- Use for prototyping UI flows and lightweight server endpoints with Express-style static JSON endpoints.
- Encourage refactors toward component-based frameworks (React/Vue) and add responsive layout, accessibility fixes, and unit/UX tests before scaling to larger projects.
