Summary
🤩
Rockstar🎓
Top SchoolMartin Lucina is a seasoned systems and security-focused software engineer with over 21 years designing hypervisors, unikernels and low-latency messaging middleware. As owner of Lucina & Associates and former kernel engineer at Docker, he has deep hands-on experience across KVM, Xen, bhyve, Solo5, MirageOS and rumpkernels, and helped pioneer early AMQP and ZeroMQ implementations. He is language-agnostic but highly practiced in C/C++, assembly and POSIX tooling, with decades of Linux/UNIX kernel and distribution work including Debian, RPM and OpenWRT. Martin’s contributions to notable open-source projects like rumprun, Solo5 and libzmq demonstrate a rare blend of boot/VM internals, secure sandboxing (seccomp) and pragmatic build-system mastery. Based in Bratislava with easy travel across Central Europe, he consults on embedded, virtualization and secure systems projects that “just work.” An unobvious strength is his long habit of solving platform-specific timing and low-level edge cases (e.g., Xen timecounters and sigtimedwait), which makes him a go-to engineer for finicky kernel and unikernel issues.
