A secure Employee Self-Service (ESS) iOS app designed to streamline HR operations and improve workforce productivity. I worked at ICTechnology Pty Ltd and contributed to TalentraSuite as an iOS Engineer.

Functionality
Core HR self-service features delivered in the app.
Submit and track leave requests with real-time approval status updates from managers.
View attendance records, monitor working hours, and track daily clock-in / clock-out history.
Approve requests and manage team activities on the go — empowering managers with mobile HR oversight.
Securely access personal information, employment records, and payslip documents anytime.
Stay informed with real-time push notifications for approvals, reminders, and HR updates.
Authentication tied to an organisation's TalentraSuite HR system — accessible only to authorised employees.
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 and async operations.
Used CoreLocation to validate employee attendance location — ensuring clock-in is recorded only from authorised premises with geofencing support.
Integrated Push Notifications via APNs to alert employees of leave approvals, attendance reminders, and HR announcements in real time.
Test-Driven Development (TDD) was the primary development approach. Unit tests written with XCTest, concentrated on the Data Layer (Repository and Data Source implementations) and ViewModels — achieving near 100% coverage on these layers. The layered architecture keeps each unit independently testable.
Structure
Clean Architecture principles — but streamlined. No dedicated Use Case layer; instead the Repository acts as the business logic boundary, keeping the architecture simple without sacrificing separation of concerns.
SwiftUI Views & ViewModels. Observes state from the Repository, handles UI events. No business logic.
Repository Protocol defines the contract. Local and Remote Repository concrete types implement it, delegating to their respective Data Sources.
Concrete implementations — Moya-backed remote API calls and local storage. Maps DTOs to domain models. Near 100% unit test coverage with XCTest.

My Role
I worked at ICTechnology Pty Ltd as an iOS Engineer on TalentraSuite — responsible for building the native iOS client. Key contributions included implementing the leave management flow, attendance & time tracking, 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 — focused on Repository, Data Source, and ViewModel layers.
Distribution
TalentraSuite is publicly available on the App Store — however, it requires a valid account provided by your employer or organisation that has implemented the TalentraSuite HR system. The app is intended for authorised enterprise users only.
