Hi, I'm Nicolai 👋

Senior iOS developer at a German security company, specializing in mobile driver’s licenses and vehicle registration certificates based on international identity standards (ISO/IEC, OIDC). Expertise in identity protocols and secure mobile solutions.

Issuing Presentation

On the side, I work on multiple projects such as Phases, a Cycle Tracker with focus on privacy, and 100 Questions, my most successful one yet - a social game that has been live since 2017 with ~30k monthly users at its peak across iOS and Android. Currently developing an ai-powered voice message processor to summarize voice messages directly from your messenger app (e.g. Whatsapp/iMessage) into a simpler text format - its name is probably the greatest part: SpareMe.

Live WIP

I've published several Swift packages from nearly a decade of iOS development, covering UIKit layout, StoreKit2 integration, camera handling, and social media uploads. Actively used in production with proven performance across multiple apps including 100 Questions and Phases.
