A workforce management iOS app for attendance tracking, clock in/out, leave requests, and HR services. I was working at ICTechnology Pty Ltd and contributed to TimeARK as an iOS Engineer.
Engineering
Technologies and frameworks used to build the iOS client.
Built entirely with SwiftUI, using declarative, state-driven UI components. All development and profiling done in Xcode.
Structured with MVVM on top of Clean Architecture, keeping Presentation, Domain, and Data layers cleanly separated and independently testable.
All API communication handled via Moya, providing a type-safe, enum-based abstraction over the network layer with clearly defined endpoint targets.
Combine for reactive data flow between ViewModels and views. async/await for structured concurrency in network requests and async operations.
Used CoreLocation to validate employee clock-in location against geofenced worksites — ensuring attendance is recorded only from authorised premises.
Integrated Push Notifications via APNs to alert employees of shift reminders, leave status updates, and HR announcements in real time.
Test-Driven Development (TDD) was the primary development approach. Unit tests written using XCTest covering ViewModels, Use Cases, and Repository implementations. The Clean Architecture layering ensured each unit could be tested in full isolation.
Structure
Dependencies only flow inward — the Domain layer has zero external dependencies, making it the most stable and fully unit-testable layer.
SwiftUI Views & ViewModels. Observes state from Domain, handles UI events. No business logic.
Use Cases & Entities. Pure Swift — framework-independent. Fully covered by XCTest unit tests.
Repository implementations, Moya API services, CoreLocation integration. Maps DTOs to domain models.

My Role
I was working at ICTechnology Pty Ltd as an iOS Engineer on the TimeARK project — responsible for building the native iOS client from the ground up. Key contributions included implementing the clock in/out flow, integrating CoreLocation for geofenced attendance validation, wiring the Moya networking layer, setting up Combine-based reactive state in ViewModels, integrating Push Notifications, and writing unit tests following TDD with XCTest.
Distribution
The iOS app is published as an Unlisted App on the Apple App Store — not discoverable through search or browse, accessible only via a direct private link provided by the client organisation. This follows Apple's approved B2B distribution model.
