What I'm looking for

I am looking for a role that fosters creativity and innovation, with opportunities for career growth and collaboration in a dynamic team environment.

I am an experienced iOS Developer with a strong background in fintech applications, dedicated to developing and refactoring code to enhance readability, maintainability, and scalability. My daily tasks involve implementing SDKs, integrating RESTful APIs, and creating custom component classes while adhering to SOLID principles. I have successfully migrated applications to upper iOS versions and have built server-driven UI components using Apollo GraphQL and SwiftUI, ensuring prompt delivery of high-quality features.

Throughout my career, I have prioritized task management strategically, blending creativity with technical expertise to deliver exceptional results. I have implemented accessibility improvements and ensured compliance with design systems, which has significantly improved app performance. My collaborative approach has allowed me to work effectively with cross-functional teams in an Agile environment, where I have investigated and resolved memory leaks using Instruments, further enhancing app performance.

With a solid educational foundation in Mechanical Engineering and extensive training in iOS development, I am proficient in various technologies, including Swift, SwiftUI, Combine, and RxSwift. I am passionate about improving code quality through SOLID-based refactoring and enforcing coding standards, and I continuously seek opportunities to leverage new platform features to enhance user experience.
