- Integrate applications with RESTful APIs and authentication services (OAuth, JWT, etc.).
- Design UI components that adapt gracefully across different screen sizes, resolutions, and device orientations.
- Write unit, widget, and integration tests to ensure reliability and stability.
State Management & Architecture
- Use Bloc (and related libraries) to manage complex state in a predictable, scalable way.
- Structure projects using clean architecture principles, separation of concerns, layered organisation, and reusable components.
- Contribute to technical decisions around architecture, performance optimisation, and lifecycle management.
Build & Release Process
- Configure build pipelines for iOS and Android, including signing, environment variables, and flavor-based builds.
- Work with CI/CD pipelines to automate builds, testing, and deployments.
- Diagnose and resolve build issues across environments (local, staging, production).
Security & Authentication
- Implement secure authentication flows.
- Follow OWASP Mobile and API security best practices to protect user data.
- Ensure sensitive data is handled safely (e.g., avoiding hard-coded secrets, secure storage, HTTPS enforcement).
Collaboration & Delivery
