Miriam Kuemmel is a technical leader and co-founder focused on building production-ready LLM applications and tooling that make complex AI reliable and accessible. With seven years of experience bridging computational linguistics and applied language modeling, she helped deploy semantic search, RAG systems, and chatbots across industries at deepset and now leads Blue Guardrails to detect and prevent hallucinations in AI systems. She combines hands-on engineering—contributing to the popular Haystack framework by improving retrieval components and pipelines—with team leadership and direct customer engagement to turn research into practical solutions. Based in Berlin, Miriam is equally comfortable debugging why a RAG system fails and managing timelines to deliver working AI in production.

AI orchestration framework to build customizable, production-ready LLM applications. Connect components (models, vector DBs, file converters) to pipelines or agents that can interact with your data. With advanced retrieval methods, it's best suited for building RAG, question answering, semantic search or conversational agent chatbots.
