Cyprien Nicolas is a systems and network engineer with 11 years of experience building and automating large-scale GNU/Linux infrastructures across research and commercial environments. He designs and maintains production environments of 100–200+ hosts, specializing in rolling upgrades, high availability web stacks (HAProxy, Varnish, nginx), and search platforms like Elasticsearch. A free-software advocate and former PhD candidate, he combines deep systems-level debugging with orchestration expertise—most recently driving Ansible-based automation and multi-version Elasticsearch migrations. He pairs academic rigour (teaching and research at Université Côte d'Azur and INRIA) with hands-on ops work, advising developers on performance and CI/preproduction pipelines. Colleagues rely on him for pragmatic architecture choices that keep services stable under heavy crawling and big-data workloads.
