Senior🎓
Top SchoolPavel Butsykin is a Senior Kernel Developer with a decade of systems-level experience spanning Linux and Windows kernel work, virtualization, storage and device drivers. He has driven high-impact features like a prefetch cache virtual block driver for QEMU, a kernel client for highly-available Virtuozzo Storage, and USB intrusion-prevention and virtual USB drivers that combine kernel and user-space components. An active contributor to libguestfs (notably v2v image conversion and UEFI/bootloader reliability fixes), he blends low-level reverse engineering with pragmatic engineering for production systems. Based in Dubai, he brings cross-platform C/C++/Go/Python expertise and a keen focus on performance, security and high-load reliability. Notably, he pairs open-source contributions with hands-on kernel debugging and live-update research, making him effective at turning obscure OS internals into robust features.
