Summary
👤
Senior🎓
Top SchoolJ Martins is a seasoned Nomad System Engineer with 15+ years of hands-on experience building and operating large-scale Linux and Solaris infrastructure across academic, enterprise and cloud environments. He helped migrate and modernize critical services at Rackspace—automating package builds and cluster bootstrapping to cut deployment time from weeks to days—and authored tools to simplify disk replacement and object-store transitions. Early career work at FAU and GeoFocus honed his kernel compiling, networking (IPv4 OSPF, IPv6 BGP) and disaster-recovery skills, and he has deep practical experience with SaltStack, OpenStack Swift/ Hummingbird, HAProxy, Graylog/ELK and VPN-linked multi-site deployments. Comfortable shipping reproducible solutions, he blends low-level troubleshooting (custom kernels, embedded systems) with automation and orchestration to reduce operational toil. Based in Amsterdam, he brings both on-call grit from Rackspace’s “fanatical” support culture and a continuous curiosity for tooling and cross-site networking that keeps complex systems reliable.
