As a seasoned and adept full-stack developer with over 5 years of experience, I am confident that I can seamlessly integrate your Flutter UI into your existing app. Throughout my career, I have honed my skills in HTML, CSS, Python, Java, Swift and more - all of which are highly relevant to the task at hand. My proficiency in Flutter, Dart, Android and iOS development makes me well-suited to handle the transfer of UI screens from one repository to another without disturbing the controllers or business logic.
In addition to enabling smooth code integration, I'm also adept at UI/UX design. Adhering strictly to existing app's themes while integrating original UI components is something I specialize in. Furthermore, my familiarity with integration testing assures you that should any problems arise during or post-transfer, I would be well-equipped to address them effectively.
Over the years, maintaining a high level of client satisfaction has been one of my top priorities. This involves not only completing tasks diligently and efficiently but also being flexible enough to offer additional support if needed – such as conducting integration testing as per your project preferences.
