At LCM Digital GmbH, I own technical direction for mobile capabilities in a B2B construction platform used across 4,000+ projects. I lead day-to-day mobile engineering while staying hands-on with architecture, debugging, and production behavior.
For very large projects, I led collaborative-state architecture using Yjs and Liveblocks, replacing full-history replay and reducing initialization from minutes to seconds. I also designed local-first and offline behavior for field users working with unreliable connectivity.
I built a production multimodal AI ticket workflow using text, photos, and voice, with Whisper transcription, GPT-4o, persistent queues, and human review. I also architected an event-driven read platform whose broader project loading became approximately 90% faster.
At OB//CC GmbH & Co. KG, I delivered client products and guided developers while remaining hands-on. I also created and shipped Unkind, a multiplayer mobile strategy game, and use AI agents for implementation while retaining responsibility for architecture, evaluation, and production quality.
