Services offered
With more than 3 years of experience in the field of iOS development, I have been a technology enthusiast since childhood. I entered the Software Engineering course, and in 2015, I had the opportunity to participate in the Apple Developer Academy, where my passion for iOS application development came to life.
During my career, I would like to highlight the completion of my undergraduate and master's degrees, the latter focusing on mobile application usability evaluation research. My dedication resulted in the title of Master and the presentation of works at international events, expanding my vision and expertise in the area.
As an iOS developer, I have proven expertise in creating mobile applications in Swift using architectures such as MVC, MVP, and MVVM-C. In addition to writing quality code, I apply best practices and development techniques such as SOLID and clean architecture.
I have extensive knowledge of relevant technologies, including RxSwift, unit testing with Quick and Nimble, Cocoapods, ViewCode (Snapkit and Anchor), XIB/Storyboard, Git, Fastlane, Firebase, voiceover, and app submission to the App Store. These skills are essential to delivering high-quality, high-performance products.
My close collaboration with UX teams has been a significant part of my professional journey. Working closely with user experience experts ensures that the applications I develop provide an exceptional experience for end users. In addition, my dedication to code quality is reflected in my active collaboration with QA professionals to ensure reliable deliveries.
