About

Making apps people love to use.

Senior Apple Platforms Engineer at Etnetera Flow in Prague. I write Swift every day: SwiftUI and UIKit for iOS, and across macOS, watchOS, and visionOS when the platform calls for it. Kotlin Multiplatform is part of the mix too.

A major focus of my work is AI standardization and governance, turning fast-moving tools into clear, responsible engineering practices that teams can use consistently, from a single mobile project to a wider domain.

When I'm not at work, I'm building Drift, a private journaling app designed around impermanence. No cloud, no accounts, no pressure.

Sharing what I learn.

Article + talk Etnetera Flow

On-device AI with Apple Foundation Models

I shipped two features into Guest Connect, Etnetera's event app, that run entirely on-device on Apple Foundation Models: an event summary and a Q&A window, both working offline with no server behind them. It started as a hands-on workshop, became production work, and turned into an App & Tell talk in Prague and this article.
