Linux Kernel Developer

Software engineer, Linux kernel developer, tech lead, storage architect. Experience in the storage industry since 2012. My project: aosto.io - software-defined composable disaggregated all-flash storage cluster. Activities: - Design and development of software-defined storage systems, including proof-of-concept, production and future releases. - Leading the software development life cycle, including requirement analysis, planning, testing and maintenance. - Team & tech leadership, mentoring, R&D, conferences, webinars. I developed: - Software storage cluster for NVMe - Software RAID for NVMe (10M iops) - Active-Active NVMe storage - Scale-out distributed storage - Mid-range hybrid storage Hard skills: - C - Linux kernel development - Storage development (architecture, performance, datapath, data services, RAID, volume manager, metadata, DPDK/SPDK, SAN, NAS, distributed scalable systems) - Algorithm development (caching, i/o and process scheduling, load balancing, distributed computing, lock-free/wait-free) - Understanding Linux internals (block i/o, scheduling, multithreading, synchronization, interrupts, memory management, filesystems, device drivers) - Understanding SCSI and NVMe technologies (NVMeoF, SCSI targets, Infiniband, iSCSI, Fibre Channel) - Hands-on experience with hardware (Intel, AMD, Mellanox, QLogic, Broadcom) - Troubleshooting and debugging (performance bottlenecks, data recovery, memory leaks, kernel panics) - High-performance, low-latency, CPU-friendly, NUMA-aware, lockless and production-ready programming Conferences: - Development of software-defined storage engine for 25 million IOPS (SNIA SDC EMEA 2021) https://cdn.hubilo.com/brochure/303037/2548_6674_887590001622997258.pdf - Reinvention of RAID for the World of NVMe (Flash Memory Summit 2018) https://www.flashmemorysummit.com/English/Collaterals/Proceedings/2018/20180808_NVME-202-2_Smirnov.pdf
