Sébastien Rombauts is a Senior Software Engineer based in Paris with 14 years of cross-disciplinary experience building robust C++ systems, game-engine tooling, and cloud-backed services. He specializes in source-control integrations and Unreal/Unity ecosystems—contributing notable open-source work like the widely used SQLiteCpp wrapper and an Unreal Git plugin that led to collaboration with Epic and a GDC invitation. At Unity he focuses on VCS integration (Plastic SCM, Perforce, Git) and full-stack services in Azure, while previous roles involved leading tools, build systems and networked gameplay for an ambitious MMO. He brings deep low-level and embedded-systems roots (Windows CE, drivers, FPGA) that inform pragmatic performance and portability fixes across platforms. Colleagues rely on him for mentoring, CI/CD design, and for translating complex engine internals into reliable tooling and plugins.
