// about

Good software does not
need to shout to work.

I build small, polished products that respect your time and privacy. No unnecessary accounts, tracking or overloaded screens.

I work on one app at a time — from the first pixel to the App Store. Every detail — a keyboard shortcut, a launch time, an empty screen — is a decision, not an accident.

focus: One app does one thing well instead of five things halfway.
privacy: Your data stays on your device. No accounts, no cloud, no exceptions.
craft: Native APIs, full keyboard control and details you only notice when they are gone.
