Flutter, plus native iOS (Swift) and Android (Kotlin/Java) since 2017: clean MVVM architecture, offline storage, push notifications and in-app purchases.
WebRTC, Agora, LiveKit and Matrix VoIP, with CallKit incoming calls, Picture-in-Picture and web-to-mobile screen share.
Agents that listen, think and talk back: Whisper, Llama, Orpheus and Piper, on LiveKit Agents or my own WebRTC pipeline.
Hands-free apps for RealWear, Moziware and ARSpectra headsets: voice commands, barcode scanning, OCR and offline mode.
End-to-end encrypted messaging on the Matrix protocol, with key backup and recovery, 2FA and push notifications.
I lead a remote mobile team at a German software company: sprint planning, stand-ups and retrospectives, with release pipelines on GitLab CI and Xcode Cloud.
Client apps are shown without their names. Open a project to see the goal, my solution and the stack.
From native iOS and Android to Flutter, real-time calls and AI.
Tell me what your app needs, and I'll reply with how I would build it before we start.
