Dear Hiring Manager, I am excited to apply for the Senior Software Engineer position at Twine. With four years of professional experience in mobile application development, I have built a strong and versatile skill set across both cross-platform and native technologies. My expertise includes .NET MAUI, Flutter, React Native, as well as native development for Android (Kotlin/Java) and iOS (Swift). This breadth of experience enables me to deliver high-quality, user-centered solutions tailored to various technical environments. In my current role, I work remotely with a US-based client, which has strengthened my ability to collaborate effectively across time zones and deliver results in fast-paced environments. Prior to my professional experience, I independently managed several freelance projects from start to finish, covering requirements gathering, development, testing, and app store deployment. This early hands-on work laid a strong foundation for my career and developed my ability to work closely with stakeholders, manage timelines, and consistently deliver polished applications. Key strengths I bring include: • Cross-Platform & Native Expertise: Building seamless, high-performance mobile applications using .NET MAUI, Flutter, React Native, and native Android/iOS tools. • Scalable Architecture: Designing and implementing solutions engineered for long-term growth, maintainability, and adaptability. • Strong Attention to Detail: Ensuring thorough testing and quality assurance to deliver stable, reliable, and user-friendly experiences.
