About Me

Passionate about creating exceptional mobile experiences

I'm a Senior iOS Developer with over 8 years of experience building apps that are fast, reliable, and user-friendly. I started my journey with Objective-C but quickly embraced Swift and SwiftUI, and now I'm diving into exciting new technologies like Spatial Programming.

Over the years, I've worked on everything from maintaining legacy code to designing scalable architectures like MVVM, VIPER, and TCA. I love using frameworks like Combine and RxSwift to make apps not only functional but also scalable, testable, modular and decoupled.

I'm passionate about solving tough technical challenges and making products that people love to use. Whether it's integrating APIs, optimizing app performance, or crafting clean, maintainable code, I enjoy every step of the development process.
