Мои компетенции и опыт

Systems C++ engineer with 4+ years in low-level storage and networking codebases. At Wellstor I build C++ services for a distributed block-storage product on top of SPDK - a disk subsystem (volume splits, RAID creation and management over RPC), a Prometheus-backed metrics service for runtime observability, a cross-node disk heartbeat for connectivity detection, and an on-disk metadata layer that lets disks recover and reconfigure on restart; I also resolved a lock-up in SPDK's NVMe path and tracked down several memory leaks with AddressSanitizer. At Huawei I worked on router firmware in C and C++: I optimized the packet-filtering hot path (longest-prefix matching for CIDR-masked rules) and cut the rule table's memory footprint, led a two-person NAT effort that added the full CLI control surface and extended ALG handling (FTP, PPTP, RTSP), and built virtual wireless connectivity inside the eNSP Pro Lite simulator using NFQ packet redirection and eBPF. Strong in modern C++ (17/20/23), concurrency and lock-free patterns, Linux/POSIX, io_uring/epoll, and thorough GoogleTest coverage, with solid debugging and profiling habits (GDB, Valgrind, the sanitizers, perf/FlameGraph). Active C++23 practitioner with several personal projects. GitHub: нужен доступ к резюме , telegram: нужен доступ к резюме
