Summary
👤
Senior🎓
Top SchoolRonan Abhamon is a virtualization and R&D software engineer with 11 years of experience, currently developing core features for XCP-ng and Xen Orchestra using C, C++ and Python. He blends low-level systems work—fixing memory leaks and improving C++ wrappers—with full-stack contributions to orchestration tooling, UX, and performance optimizations for VM monitoring and backup. Previously he built Linphone Desktop from scratch, designed plugin systems for SIP servers and authored a generic C++11-to-C wrapper, showing strong cross-language and protocol expertise. Based in Saint-Genest-Lerpt, France, he pairs academic grounding (Master in Computer Engineering) with practical open-source impact, visible on GitHub contributions to well-known projects like liblinphone and xen-orchestra. Notably, he focuses on long-lived maintainability improvements (shared PImpl management, session handling) that reduce leaks and simplify evolving codebases.
