Cyril Roelandt is a software engineer with 12 years’ experience specializing in backend development and Python migrations, currently based in the Greater Bordeaux area and working at eNovance/Red Hat. He is an active open-source contributor to major OpenStack projects (Keystone, Neutron, Glance, Swift, Tempest, Ceilometer), where he focused on Python 3 porting, byte/string correctness, and hard-to-catch runtime and test-suite fixes. His background in systems and runtime work (INRIA’s StarPU) and teaching operating systems gives him strong foundations in low-level concerns and performance-aware engineering. Cyril also improves developer tooling and CI quality—adding static analysis and test automation to projects—to reduce regressions in large codebases. Notably, he has addressed subtle interoperability issues (EC2 signing, requests/httpretty encoding) that often block cross-version compatibility. He combines rigor in maintenance and testing with practical experience shipping compatibility improvements across widely used cloud infrastructure.
