Stephen Gelman is a Platform Architect with 13+ years building and operating large-scale, production infrastructure, currently leading platform efforts at Braintree and contributing as a Debian Developer. He combines deep systems engineering—spanning mail systems, virtualization, SANs, AD, Puppet, and cluster/HA tooling—with software skills in Python, Java, C and shell to automate and harden complex environments. A pragmatic leader who progressed from production engineer to group technical lead and architect, he’s shipped virtualization and Puppet-based provisioning that reduced costs and accelerated deployments. He’s an active open-source contributor with practical fixes to widely used projects like git-lfs and the Puppet Dashboard, showing attention to maintenance, dependency hygiene, and reporting correctness. Based in Chicago, he brings a rare mix of hands-on recovery experience (bare-metal Zimbra restores, PBX rebuilds) and long-term platform planning.
