Overview

11 years in software engineering, the last 4 at Trade Republic, where I lead the ML platform team. Brought on-call pages for ML platform down from 36 a week to 2. Reduced cloud spend on ML platform by 28% in two quarters. Before that: Société Générale and Roche. Most at home with feature stores and PyTorch.
