Summary
👤
Senior🎓
Top SchoolFrédéric Yhuel is a PostgreSQL Support Engineer with 14 years of experience building and tuning data-intensive systems, currently helping users and organizations at Dalibo. He cut his teeth on high-performance C systems and large-scale search at ANSSI, where he developed a multi-threaded n-gram indexer and deployed ElasticSearch and sharded PostgreSQL clusters with HA in production. Comfortable across C, Python and database internals, he brings deep performance and operational expertise—particularly in database tuning, indexing strategies and distributed deployments. Based in Brest, France, he blends an open-source mindset with formal training in cryptology and security engineering, which informs a careful, security-conscious approach to data infrastructure. A less obvious strength is his background in multimedia and IDS research, giving him a systems-level perspective that helps diagnose subtle cross-stack issues.
