Senior🎓
Top SchoolJames Swaro is a Principal Software Engineer with 14 years of deep expertise in Linux, high-performance networking, and RDMA technologies, currently driving networking stack architecture at Hewlett Packard Enterprise from Lillerød, Denmark. He has led cross-functional teams on large-scale products like Slingshot and Shasta, delivering performance and scalability improvements while coordinating vendors and contractors. A long-term contributor and maintainer to the widely used OFIWG/libfabric project, he has implemented low-level atomic operations, improved memory registration caching, and fixed core error handling to boost library reliability and throughput. His background includes significant systems-level work at Cray, where he reduced emulation memory footprints by up to 80% and improved TCP performance by as much as 80% through kernel- and user-space innovations. James combines hands-on low-level coding with technical leadership and research experience, including published work on libfabric and dynamic RDMA credentialing. Colleagues rely on him for pragmatic design trade-offs that advance both product roadmaps and open-source ecosystems.
