• Develop and maintain technical documentation, such as design specifications, user guides, and release notes

• Lead and execute the migration of existing functionalities written in Swift to Flutter, ensuring seamless integration, optimal performance, and maintaining a consistent user experience across platforms

• Develop complex mobile applications using Flutter and Dart, with 3+ years of hands-on experience and a total of 5+ years in client application development.

• Demonstrate expertise in state management with BLOC, networking with GraphQL and Dio, and creating intuitive and efficient UI/UX components.

• Apply OOP principles in writing clean, maintainable, and scalable code using Swift, Kotlin, and Dart.

• Write and maintain unit and widget tests to ensure code reliability, with experience in tools such as Patrol and Maestro considered a plus.

• Apply best practices in mobile app development, including performance optimization, security, and accessibility.

• Work within a Continuous Integration/Continuous Deployment (CI/CD) pipeline and collaborate using agile development methodologies.

• Display excellent problem-solving skills, breaking down complex issues and delivering practical solutions.

• Communicate effectively with diverse teams, contributing to collaboration and knowledge sharing across the organization.

Nice-to-Have Skills
