Summary
🤩
Rockstar🎓
Top SchoolTommaso Teofili is a principal software engineer with 16 years of experience building scalable search, IR and ML systems, now focused on vector search and generative AI at Elastic. He combines deep open-source pedigree—as a long-time Apache committer and PMC member across Lucene, Solr, OpenNLP and more—with hands-on contributions to high-profile projects like Elasticsearch and Lucene that added KNN vector support and tokenization/analyzer improvements. His background spans research and product engineering roles at Red Hat and Adobe, where he worked on explainable AI, document and image embeddings, and production search/indexing platforms. Tommaso’s work bridges research and engineering: he implements algorithms (query-likelihood models, ANN techniques) and hardens them with tests, refactors and integration work. Based in Rome and pursuing AI research at a PhD level, he pairs solid systems craftsmanship with a curious, research-driven mindset. Off the beaten path, his GitHub bio “ball don't lie” hints at a pragmatic, results-first approach to solving hard problems.
