Dear Hiring Manager,
I am writing to express my interest in opportunities within mobile application development. With over 10 years of experience as a native iOS developer and newly expanded skills in Flutter and Dart, I offer a strong blend of technical expertise, product ownership, and cross-functional collaboration.
Throughout my career, I have built and maintained high-quality mobile applications for major clients across banking and financial domains. I have worked closely with product managers, backend teams, and QA engineers to deliver secure, scalable, and user-focused app experiences. My responsibilities have included leading feature teams, mentoring junior developers, reviewing code, managing releases, and ensuring smooth delivery across UAT and production environments.
My technical expertise spans Swift, Objective-C, UIKit, SwiftUI, MVVM, Clean Architecture, CI/CD pipelines, Firebase Analytics, Google Analytics, SonarQube, and App Store deployment. I have consistently contributed to improving code quality, system performance, and feature delivery timelines.
In addition to my iOS background, I have recently strengthened my capabilities in cross-platform development. I completed the “Flutter & Dart – The Complete Guide [2025 Edition]” and have since developed several personal and freelance Flutter projects. These projects helped me gain hands-on experience with responsive UI design, Firebase integration, REST API communication, state management, and multi-platform application flows.
I am eager to contribute my skills to a team seeking a versatile, detail-oriented mobile developer who can deliver high-quality features, collaborate effectively, and adapt to new technologies quickly. I am confident that my combination of native iOS experience and growing cross-platform expertise enables me to add value in a wide range of mobile development roles.
Thank you for considering my application. I look forward to discussing how my background and skills can contribute to your team.
Warm regards,
Thivya Ponnusamy
