Berlin · iOS since 2010
I’m a senior iOS engineer drawn to the parts of an app people only notice when they go wrong: the music player at IDAGIO, real-time ride matching at Volt, an AR app at Scandit that knows which shelf a barcode sits on.
Owned IDAGIO’s player SDK; playback complaints fell 95% in six months.
Re-architected Volt’s ride matching around a real-time Firebase view layer.
IDAGIO · 2018 – 2022
I owned the player SDK of the classical-music streaming service IDAGIO, implementing the gapless, lossless playback that classical listening demands, rebuilding buffering, and turning the player into a proper standalone SDK.
Gapless, lossless playback shipped, still the product's signature
Scandit · 2022 – 2024
At Scandit I built a SwiftUI AR app from scratch that matches barcodes scanned with the Scandit SDK to shelves mapped in AR. Alongside it, I integrated and maintained the SDK across mobile platforms and WebAssembly, and contributed to its C/C++ core.
Built from scratch in SwiftUI and ARKit
Volt · Jan – Jul 2016
Volt's inner-city ride sharing matched riders to drivers through a polling REST backend, and felt every second of it. I re-architected matching around Firebase as a client-facing view layer over the existing backend.
Average match time cut from minutes to under 5 seconds
Hipo (client project) · 2014 – 2015
At product studio Hipo I built consumer iOS apps from scratch in Objective-C (blogTO, FoodTruckTO) and Moment, a private photo-sharing app for families, told here in depth.
