Summary
🤩
Rockstar🎓
Top SchoolGal Pressman is a Software Development Manager specializing in the Linux kernel with nine years of experience building and leading low-level networking and driver development. Currently at NVIDIA after roles at Amazon and Mellanox, he has deep expertise in RDMA, EFA/ENA drivers and kernel networking features, and has contributed fixes and performance improvements to the mainline Linux tree. His open-source work includes notable commits to torvalds/linux, iproute2, and Amazon's amzn-drivers where he modernized driver architecture, fixed critical race/interrupt bugs, and improved kernel APIs usage. Gal balances hands-on systems coding with technical leadership, guiding teams to deliver robust, production-grade kernel components for high-performance networking. Based in Israel and educated at the Technion in software engineering, he brings both device-driver craftsmanship and system-level architecture to complex network stacks. An uncommon strength is his ability to refactor legacy kernel code into safer, modular implementations while preserving performance in latency-sensitive paths.
