Hi, I’m Alexander Atanasov, a highly experienced Linux kernel and embedded systems engineer with 25+ years of hands-on work across the HW–kernel–userspace stack. I specialise in Linux driver development, virtualization, performance tuning, and building customised embedded Linux distributions, with a track record of upstream-quality, reliable code. I’ve led kernel storage, networking, and memory-management work, invented ESFQ, and I bring strong debugging skills to complex hardware bring-up and cross-functional collaboration. I also build and customise open source and vendor BSPs (OpenWrt, Buildroot, Yocto, Raspberry Pi OS), and I thrive in fast-moving environments delivering robust systems.…Hi, I’m Alexander Atanasov, a highly experienced Linux kernel and embedded systems engineer with 25+ years of hands-on work across the HW–kernel–userspace stack.
