About Me

I'm an AI Engineer & Software Architect specializing in embeddings, RAG (Retrieval-Augmented Generation) systems, and AI agent development. Currently working at Deka Bank in the AI domain while maintaining my role at adesso SE. With over a decade of experience spanning fullstack development, CI/CD, and cloud architecture, I focus on building intelligent systems that combine cutting-edge AI technologies with robust, scalable software architecture.

My expertise lies in implementing production-ready AI solutions, from semantic search and vector databases to complex multi-agent systems. I'm passionate about prompt engineering, knowledge management systems, and creating AI applications that solve real-world business challenges. When I'm not architecting AI solutions, you'll find me exploring the latest developments in LLMs, contributing to open-source projects, or sharing insights with the developer community.
