Senior🎓
Top SchoolTheodoros Tsioutsias is a senior software engineer with a decade of experience building production-grade systems in C and Python, currently driving engineering at Pictet Group. He has deep expertise in distributed cloud infrastructure, having contributed upstream to OpenStack Magnum and implemented orchestration and Nova changes for pre-emptible instances at CERN. Previously he led performance and configuration subsystems for Nokia Gateway, mentoring teams and designing a cloud scaling framework, and spent four years in quantitative engineering at a hedge fund. Known for shipping pragmatic, quality-oriented solutions under tight deadlines, he combines systems-level debugging skills with API and orchestration design. His open-source work on Magnum—improving nodegroup support and Heat integration—reflects a strong appreciation for interoperable, deployable infrastructure. Based in Geneva, he pairs hands-on implementation with a habit of formalizing operational practices that survive team turnover.

Contributions summary:Theodoros's primary contributions involve enhancements to the OpenStack Magnum project's core functionality, specifically focusing on container infrastructure management. Their work includes addressing and resolving issues related to `FakeLoopingCall`, enhancing the nodegroup representation, adapting existing cluster APIs and the conductor to incorporate nodegroups, adapting the existing drivers, creating APIs for listing and showing nodegroups, adapting the cluster object, hardcoding the names of the default NGs, and modifying the heat template. These changes suggest a strong understanding of Magnum's architecture and its interaction with Heat.
