Viktor Nawrath
Principal Engineer · Head of AI Engineering @ profiq
Full-stack engineer, 10+ years shipping production systems end to end — now leading AI engineering at profiq, still hands-on across the stack. Built Sliders: a music player and recommender running on a 38M-parameter audio embedding model I trained myself, live in production. I set technical direction and write the code that proves it.
