​I don’t just build AI. I build production-grade, reliable systems that solve complex business problems. ​With over 15 years of experience in software engineering-ranging from low-level optimization at Samsung to financial data architecture at UBS I bring a level of engineering discipline to the AI space that is rare to find. ​Currently, at Bayer, I focus on the cutting edge of Agentic Workflows using LangGraph. I specialize in transforming unpredictable LLM outputs into stable, state-aware, and auditable business processes. ​My core expertise includes: 🤖 Agentic Orchestration: Designing complex, multi-agent systems with LangGraph, focusing on persistence and human-in-the-loop safety. 🚀 AI Efficiency: Leveraging my background in Caffe2/PyTorch optimization for ARM to build high-performance AI solutions. 🏗️ Enterprise Scalability: Scaling AI applications within Azure environments, ensuring they meet the highest standards of data integrity and reliability. 📊 AI Observability: Implementing rigorous evaluation frameworks (Ragas, LangSmith) to ensure AI systems are production-ready and hallucination-free. ​I am a Master-level Sailor and Ultra-cyclist. In both sports and engineering, I believe in resilience, meticulous preparation, and the ability to navigate through high-pressure environments. ​If you are looking for an AI Architect who understands that "it works on my laptop" is not enough for the enterprise-let’s connect.
