Top SchoolRicardo Koller is a Senior Software Engineer with a decade of experience building low-level systems around Linux, virtualization, and secure containers, currently at Google in the Greater Seattle Area. He brings deep C and OS expertise from roles at IBM Research and VMware, where he focused on kernel-adjacent infrastructure and research-driven engineering. Ricardo contributes to notable open-source unikernel work (Solo5), adding clock integration, wall-time and CPU-blocking features, and modular refactors that improve maintainability and realism in sandboxed execution. His background includes a PhD-level research trajectory and practical industry internships, giving him a rare blend of academic rigor and production delivery. Colleagues rely on him to navigate tricky concurrency and timing issues in constrained execution environments while keeping codebases clean and modular. Outside the obvious, he has repeatedly translated research prototypes into hardened system components used by broader virtualization ecosystems.
