Summary
👤
SeniorMathieu Bultel is a Principal Software Engineer with 15 years’ experience building and hardening cloud, devops and Linux-based systems from Paris, currently contributing to Red Hat’s OpenStack, OpenShift and Kubernetes efforts. He blends deep systems and release engineering expertise—packaging, PXE/KickStart automation, CI/CD and OpenStack image work—with hands-on open source contributions to projects like SleekXMPP and the Dolphin emulator, where his low-level fixes improved stability and protocol support. His background in QA and release management means he approaches platform work with a strong emphasis on reliability, test automation and reproducible deployments. Comfortable across Python, C and tooling around libusb, Ansible and Puppet, he repeatedly turns tricky integration issues into maintainable solutions. A less obvious strength is his history of building custom performance and testing tools (from twisted-based HTTP recorders to Selenium frameworks), showing a practical maker mindset beyond architecture.
