Bartosz Szczepanek is a Senior Software Engineer with 11 years of experience specializing in low-level systems, firmware and hypervisor development. He has driven foundational work on EC2 Nitro’s KVM-based hypervisor at AWS, leading a team of six to deliver a performance-critical core revamp across kernel and userspace. Earlier roles include firmware and UEFI/ARM Trusted Firmware development for Marvell/Cavium, where he upstreamed FreeBSD drivers and implemented measured-boot and secure update mechanisms. Based in Krakow, he blends formal theoretical computer science training with hands-on platform bring-ups and cryptographic verification implementations. Comfortable spanning firmware-to-cloud stacks, he’s known for shipping upstreamable, standards-aware solutions that bridge platform integrity and large-scale virtualization. An appetite for plumbing-level problems means he often tackles the least-visible but most consequential pieces of system software.
