About
I am a Senior iOS/Flutter Engineer with over 17 years of experience specializing in mobile development. Over the last 8 years, I have focused on iOS development using Swift, and for the past 4 years, I have been immersed in Flutter, mastering Dart to create high-performance cross-platform apps. I excel in building robust, efficient, and scalable native applications, with a deep understanding of optimizing code for maximum performance.
My experience spans backend development, agile methodologies, and delivering projects on time and within scope. I have a proven track record of collaborating with cross-functional teams, including clients, designers, and QA, to refine UX design and implement JSON structures effectively.
