Summary
👤
Senior🎓
Top SchoolPierre Letessier is a seasoned AI leader with 11+ years building production-grade machine learning and computer vision systems at INA, where he now heads an AI tribe responsible for deploying on-prem facial recognition and multimodal knowledge graph services. He combines deep academic roots in computer vision (PhD-level work) with hands-on infrastructure skills—managing bare-metal clusters, CI/CD, Docker microservices, Kafka, Neo4j, Elastic and monitoring with Zabbix/Ansible—to turn research prototypes into scalable products. His current Ogmios project links Wikidata-like entities to hundreds of millions of video fragments to improve face clustering through human-in-the-loop feedback, reflecting a pragmatic focus on data collection and representativeness as much as model accuracy. Comfortable recruiting, defining strategy and managing budgets, he blends research publications and long-term R&D experience with day-to-day ops responsibility, a combination that helps bridge ML science and production engineering.
