1. Development Environments:

•    Development Environments

o    Android studio

o    Xcode (occasionally used for iOS tasks)

•    Programming Languages:

o    Kotlin and Java

o    Swift (basic knowledge for iOS tasks).

o    C# or at least basic knowledge how a backend architecture works

o    basic SQL

•    Android UI

o    Jetpack Compose (modern declarative UI),

o    XML Views (for legacy components),

o    ViewBinding (for legacy components),

o    LiveData/Stateflow collecting

o    SwiftUI (basic for iOS updates).

•    Navigation Component: Managing navigation between screens and deep links.

•    Dependency Injection: Dagger for dependency management

•    Networking: Retrofit for REST API communication.

•    Data Storage: Room database for offline storage

•    WorkManager for background tasks.

•    ProGuard and R8: Code shrinking, obfuscation, optimizing APK build sizes.

•    Asynchronous Programming: Primarily Coroutines, with remaining use of Observables.

•    Testing:

o    Espresso (integration testing)

o    Robolectric, Mockito/MockK (unit testing).

•    Messaging and Notifications: Firebase Messaging for real-time notifications.

•    Camera APIs: Image handling using CameraX .

•    CI/CD: Azure Pipeline for managing builds and deployments.

•    Authentication and User Management: Microsoft Authentication Library (MSAL) for user authentication and managing accounts/roles in Azure DevOps.

•    Google Play Console: Release management

•    Architectures: Experience with

o    Model-View-Presenter (MVP)

o    Model-View-ViewModel (MVVM).

2. Activities done on the daily routines.

•    Translating business requirements into user stories.

•    Implementing Android app solutions based on the defined user stories.

•    Occasional iOS development (one iOS Developer, sometimes needs support – not a must)

•    Fixing data-related issues ensuring data integrity.

o    involves SQL database skills and knowledge of the backend architecture

•    Reviewing pull requests to maintain code quality

•    participating in refinement meetings.

•    Setting up and maintaining user accounts/roles and permissions in Azure DevOps.

•    Assisting users (team-members, planners, mechanics, SMP, meetbedrijf) and incorporating feedback.

o    Talking to mechanics, planners

3. Technical Debt /Skills

•    Completing the migration from Observables to Coroutines.

•    Modernizing XML-based views to Jetpack Compose where feasible.

•    Refining and maintaining authentication and user management configurations in Azure DevOps.

•    Kotlin/Java for Android development, with basic Swift/SwiftUI knowledge for iOS.

•    Experience with Dagger, Retrofit, Room, Firebase Messaging, ViewBinding, and WorkManager.

•    Familiarity with testing tools (Espresso, Robolectric, and MockK), CI/CD pipelines (Azure DevOps), and SQL for debugging backend issues.
