About this gig

I will improve, update, and modernize your existing mobile application based on your requirements.


Whether you need new features, UI/UX improvements, bug fixes, API integrations, performance optimization, or code refactoring, I can work directly with your existing project and integrate the changes without unnecessarily disrupting the current functionality.


I work with Android, iOS, and cross-platform applications using technologies such as Kotlin, Java, Swift, Objective-C, Flutter, and Jetpack Compose. Depending on your project needs, I can update existing screens, develop new user flows, integrate REST APIs, Firebase services and third-party solutions, improve application performance, and resolve technical issues.


I focus on clean, maintainable, and scalable implementation while preserving the existing application's business logic and architecture where appropriate.


The final scope, delivery time, and pricing depend on the complexity of the existing application and the requested changes.
