Summary
👤
Senior🎓
Top SchoolLenny Szubowicz is a Principal Software Engineer at Red Hat with over 40 years of systems and firmware experience and 12 years focused on RHEL kernel platform enablement. He specializes in low-level kernel development—UEFI, ACPI, suspend/resume, x86 fault handling—and brings deep expertise in storage, multipath, device drivers, file systems, and transaction journaling. Much of his career was spent leading and consulting on OpenVMS kernel engineering at DEC/Compaq/HP, giving him rare insight into legacy enterprise OS internals alongside modern Linux kernel practices. He is fluent in C, assembly, Bliss and C++, and known for solving complex platform reliability and boot-time issues. Based in Amherst, NH, Lenny blends institutional knowledge from decades at major hardware and enterprise OS vendors with current open-source kernel work at Red Hat. An uncommon strength is his cross-generational perspective on system design, from early VMS kernels to contemporary Linux platform enablement.
