What I'm looking for

I am looking for a dynamic team where I can leverage my iOS development skills, contribute to innovative projects, and grow professionally while delivering exceptional user experiences.

As an experienced iOS Developer with over five years in the industry, I specialize in designing, developing, and optimizing mobile applications. My expertise lies in Swift, SwiftUI, and various architectural patterns such as MVVM, VIPER, and CLEAN. I am dedicated to delivering high-quality, user-centric solutions that focus on clean, maintainable code.

Throughout my career, I have successfully led teams and implemented innovative features that enhance application performance and scalability. At Unlimited Technology, I designed the MVVM architecture for the HighShop App, which significantly improved code modularity and reusability. My commitment to excellence is evident in my ability to reduce application errors by 95% through code optimization and automated testing.

I thrive in collaborative environments, working closely with project managers and QA testers to ensure high-quality deliveries. My passion for mobile development drives me to stay updated with the latest technologies and best practices, ensuring that I consistently provide top-notch solutions that meet user needs.
