Senior🎓
Top SchoolLiran Oz is a software engineer with 11 years of experience building high-performance networking and file-sharing systems, currently contributing to Apple's Network File Systems team on NFS and SMB across kernel and user-space. He brings deep systems expertise from Mellanox, where he improved RDMA-based user-space networking (libvma) for low-latency multicast, UDP and TCP streaming used in finance and large-scale clusters. Practical and self-directed, he excels at debugging low-level networking issues, performance tuning, and adding robustness features like software checksum validation. His background in math and computer science and early teaching roles underpin a methodical approach to complex problems and clear technical communication. A former platoon leader in the Israeli Air Force, he combines disciplined leadership and independent ownership with hands-on engineering. Based in Israel, he blends production-grade kernel/user-space experience with a track record of open-source contributions to networking primitives.
