I'm a Senior iOS Engineer focused on building maintainable, reliable and user-centered applications for the Apple ecosystem.

My main areas of interest are Swift, SwiftUI, Swift Concurrency, application architecture and AI-assisted software engineering.

• Swift & SwiftUI
• UIKit
• Swift Concurrency
• Combine
• MVVM & Clean Architecture
• Dependency Injection
• XCTest & Swift Testing
• Modular iOS architectures
• App Store & App Review
• Privacy Manifest & Required Reason APIs
• Firebase & Analytics
• CI/CD
• AI-assisted development with tools such as Codex and Claude Code

I'm currently exploring how AI changes professional software engineering, especially in the context of iOS development.

Topics I'm particularly interested in include:

• AI-assisted coding workflows
• Coding agents
• MCP and agent tooling
• Spec-driven development
• AI-supported code reviews
• Automated testing and refactoring
• Modern Swift and SwiftUI architecture

I regularly write about software engineering, iOS development and technologies around the mobile ecosystem.

Topics include:

• Swift & SwiftUI
• iOS architecture
• App Store development
• Privacy Manifest
• AI-assisted software engineering
• Apple platform development
• Mobile ecosystems such as HarmonyOS

Good software should not only work.

It should be:

• understandable
• maintainable
• testable
• reliable
• respectful of its users

I enjoy turning complex technical problems into pragmatic solutions that teams can maintain over time.
