What I'm looking for

I'm open to remote roles with EU or US East Coast overlap where I can build production full-stack systems, real-time products, and AI-powered features.

At Haufe Group, I build React, Node.js, PostgreSQL, and AWS features for enterprise products, including semantic validation for AI-generated sustainability reporting items and an AI agent harness for specialized workflows.

Previously, I built real-time flight operations software used by 10+ airlines, launched a dietitian platform for 50k+ active users, and co-created a Shopify app adopted by 1,000+ stores. I focus on systems that perform under real-world load, backed by testing and CI/CD.
