• Strong understanding of Flutter's core concepts (widgets, state management, navigation, animations).

• Solid understanding of native mobile app lifecycles (iOS and Android), SDK integration, and platform constraints.

• Understanding of performance best practices, identifying bottlenecks, and optimizing app performance.

• Understanding of local storage solutions (like SQLite) for storing and managing data locally.

• Experience integrating RESTful APIs and authentication mechanisms in mobile apps.

• Proven background in at least one Flutter-based production deployment at scale. Proficiency in performance tuning, offline capabilities, local storage, threading, and security best practices.

• Proficient in DevOps concepts (e.g., GitLab CI/CD, Firebase, Bitrise) and test automation for mobile.

• Excellent problem-solving skills and debugging techniques across hybrid/native integrations.

• Strong English communication skills (verbal and written) with ability to clearly articulate technical issues and decisions.

Additional Skills :

• Experience with Backbase platform SDKs and digital banking implementation projects.

• Experience with building apps for both Android and iOS.

• Familiarity with strategies around native SDKs for use in hybrid frameworks.
