Deep expertise in systems programming in C and Python (low-level networking and hardware-facing code), Linux internals (kernel modules, drivers, device enumeration, debugging below userspace), and PCIe system architecture (topology, addressing, peer-to-peer, virtualization, and passthrough). Demonstrated experience in high-performance networking (kernel-bypass packet processing, hardware offload, line-rate data paths), out-of-band management (BMC and REST-based interfaces with automation), and cross-disciplinary collaboration with hardware and mechanical engineers.
