Senior iOS developer specializing in Swift, SwiftUI, and production-grade Apple-platform apps. I’m deeply specialized in SwiftUI and have pushed it to its limits across complex production apps: custom layouts, advanced state management, async data flows, navigation, animations, performance tuning, UIKit/AppKit interop, and large modular codebases. I help founders and teams turn product ideas into polished, maintainable iOS/macOS apps. My work usually spans architecture, implementation, UX judgment, debugging, integrations, and release readiness. I’m especially strong with offline-first apps, realtime sync, Apple ecosystem integrations, extensions, widgets, Siri/Shortcuts, Spotlight, and AI-powered product features. Clients usually bring me in when they need more than ticket execution: someone who can take initiative, make sound technical decisions, improve the product experience, and ship reliably.

Client reviews Ivan, Impulzity "Impressed on the detail quality not only on the functional side, but also on the visuals! Besides, transparent and direct in communication and results. Well done, any time again!" Mike Lanza, Streetography "Streetography employed Bee Wise as its mobile app developers from 2016 to 2019. It's been a wonderful relationship, and Bee Wise has performed extremely well. During those three years, they took over and completely rewrote our iOS and Android apps, and added many significant new features. They learned Android development during working for us, and became a fabulous one-stop mobile software development shop. They're amazingly independent and responsive, and need very little direction. Literally, I ask them to implement something on both platforms, and they do it. Thanks, guys!"
