Rockstar🎓
Top SchoolStefano Fiorucci is a Senior Software NLP Engineer with 7 years of experience building production-ready language model applications and information extraction systems, currently contributing to deepset’s Haystack open-source framework. He blends back-end and DevOps skills—Dockerized Tika servers, crawler improvements, and an InMemoryKnowledgeGraph—with hands-on ML work using Hugging Face, Sentence Transformers, and vLLM. Previously at 01S he turned unstructured documents into accessible information for Italian citizens, and he maintains community-focused contributions to educational repos like mrdbourke/pytorch-deep-learning. Based in the Greater Perugia area, he pairs a civil engineering background and formal AI training with a practical curiosity for deployment, retrieval systems, and scalable LLM tooling.
