Summary
👤
Senior🎓
Top SchoolElad Persiko is a systems-focused software engineer with nine years of experience specializing in networking, Android internals, and kernel-level performance optimization. He has designed and implemented data-path architectures across L2/L3/MPLS on packet processors (Broadcom, Marvell, Dune) and optimized NIC drivers and RDMA stacks—contributing performance improvements to the high-profile open-source UCX project. His Android work spans networking, TrustZone-based security, virtualization, and media playback acceleration, often touching both SDK/NDK user space and kernel subsystems. At companies from Mellanox and Alibaba to Argus, he’s delivered measurable throughput and memory improvements (THP, ODP), CPU/cache optimizations, and a pending patent on packet transmission control. Comfortable across C/C++ on Linux and VxWorks, he blends deep low-level expertise with practical experience deploying performance-sensitive systems on devices, cloud, and bare metal.

Performance EngineerContributions:27 commits, 34 PRs, 86 comments in 3 months
Contributions summary:Elad focused on optimizing the performance of the UCX library, primarily by modifying code related to InfiniBand (IB) and RoCE (RDMA over Converged Ethernet) transport layers. Their contributions included adjustments to bandwidth estimations, latency limits for testing, and device affinity to improve communication efficiency. The commits demonstrate a focus on improving the performance of the UCX library, particularly for high-performance computing (HPC) environments. The user also made changes to memory allocation strategies, including transparent huge pages (THP).
