Summary
🤩
Rockstar🎓
Top SchoolWill Jhun is a systems-focused software contractor with seven years of modern experience and a two-decade background in kernel, networking, and embedded systems design. He has led principal-engineer efforts on unikernels and ML runtimes—implementing Linux syscall emulation, virtio drivers, demand paging and multithreaded C/C++ runtimes for PyTorch graph compilation—while shipping bare-metal bringup and ARM64 ports. His open-source contributions to the nanovms/nanos unikernel include virtual memory, signal handling, in-kernel TCP and Xen integration, reflecting deep low-level expertise that spans assembly to Go tooling. Will consults for early-stage startups on high-performance compute, compiler benchmarking (IREE), and optimized container deployments for AI workloads. Comfortable across firmware, device drivers, and accelerator-aware GPU runtime prototypes, he combines pragmatic delivery with research-grade prototypes—he also holds a patent for unikernel-based multi-process hypervisor management. Based in the New York City area, he brings a rare blend of production networking experience (Cisco-era router platforms) and cutting-edge ML systems performance work.
