Rockstar🎓
Top SchoolFabio Ercoli is a Principal Software Engineer at Red Hat specializing in AI, data science and large-scale distributed systems, with a deep background in NoSQL and data grid technologies. He designs and implements scalable AI/ML workflows—particularly vector/semantic search and Retrieval-Augmented Generation—bringing production-focused engineering to research-driven features. A long-time contributor and former core team member of Infinispan and Hibernate, he has repeatedly improved search, caching and persistence layers across widely used open-source projects. His career blends domain-driven design practice since 2008 with hands-on work porting and modernizing storage dialects and timeout/scroll optimizations in Hibernate modules. Based in Rome, he combines system-level performance tuning with active exploration of neural reasoning, knowledge representation and semantic technologies. Notably, his open-source contributions span both back-end persistence internals and full-stack demo applications, demonstrating breadth from low-level database mechanics to user-facing features.
