Summary
🤩
RockstarIvan Efremov is a systems software engineer with eight years of hands-on experience building low-level infrastructure in C/C++ across Linux kernel, device drivers, storage and virtualization domains. He has shipped production storage and PCIe fabric features at DDN and YADRO, worked on type-2 hypervisor and virtio/vfio GPU stacks at Samsung, and recently joined Databricks after Neon’s acquisition. Based in Limassol, he combines embedded and high-performance server experience—from DRM/KMS GPU modules and Fibre Channel/SCSI drivers to RDMA and non‑transparent bridging on OpenPOWER—with a research background toward a PhD in systems and networks. Notably, he bridges deep kernel-level engineering and performance tuning for distributed storage and virtualized workloads, making him effective on both firmware-level problems and large-scale system integrations.
