Hi, my name is Artem Selivanov. I'm software engineer with a decade of hands-on experience in designing, developing, and maintaining successful, user-friendly, native iOS/iPadOS/tvOS/watchOS applications in such areas as Health and Wellness, E-commerce, Education, Social Networks, Messaging, Media, Streaming. I have a product-oriented mindset, focused on delivering features to production. Always looking to analyze and solve complex problems, while paying attention to fine details. Constantly learning new technologies, and thriving for excellence. I can be a part of a team, or working solo. As an iOS/iPadOS/tvOS/watchOS Software Engineer I can be responsible for an any part of your app development, maintenance or evolving cycle. Beginning from designing app architecture and UI/UX, ending with app distribution. If you need build an app of any complexity from scratch, make overall refactoring, fix broken functionality of an existing app or add new features to it, please feel free to contact me. Also I am able to integrate CI/CD automation to your project. Besides I can help you with understanding of Apple Human Interface Guidelines and give remarks or suggestions about UI/UX if needed.
