AI Applied Scientist @ SylloTips | Ph.D. in Artificial Intelligence @ Sapienza University of Rome
👋 Hi! I’m an AI Applied Scientist at SylloTips in Rome, where I build production systems that bridge academic research and real-world applications. My work focuses on developing human-in-the-loop AI agents, retrieval-augmented generation systems, and fine-tuning multilingual LLMs at scale.
🎓 Research & Engineering
I earned my Ph.D. in Artificial Intelligence at Sapienza University of Rome, specializing in multilingual NLP and advanced machine learning. My industrial Ph.D. was conducted in collaboration with Babelscape, where I gained hands-on experience turning research into production systems—prioritizing both theoretical rigor and practical deployment.
Current Areas of Focus:
🚀 Featured Projects
Beanis — Redis ODM for Python
A high-performance Redis Object-Document Mapper that reduces boilerplate by 70% while maintaining performance within 8% of raw Redis. Built for developers who need type safety without sacrificing speed.
Word Sense Linking — ACL 2024
Research on automatic disambiguation that works on real text, not just controlled examples. Tackles the challenge of understanding context-dependent word meanings at scale.
Production RAG Systems
Building retrieval-augmented generation pipelines that developers can actually deploy and maintain in production environments with real-world constraints.
💡 I enjoy collaborating with cross-functional teams and mentoring engineers at all career stages. When I’m not writing code or papers, I’m usually exploring new ideas in AI or sharing what I’m learning through blog posts and open-source contributions.
