About

I'm a Senior iOS, macOS & Android Developer with 7+ years of experience building high-performance, scalable apps with 5M+ downloads.

I work mostly in Swift, SwiftUI, AppKit, UIKit, Kotlin and Jetpack Compose, and I care about fast, smooth interfaces and code that stays easy to grow.

Most of my time goes into performance, multi-threading (GCD, async/await), security and CI/CD automation.

I also enjoy mentoring developers and improving app architecture, balancing maintainability with shipping speed. My goal is simple: mobile apps that feel fast and are easy to use.
