Summary

Rockstar🎓
Top SchoolAaron Schaefer is a seasoned Linux systems engineer with 18 years of professional experience designing and operating infrastructure across universities, startups, and consulting engagements. He specializes in automation, security, cloud architectures (AWS), configuration management (Ansible/Chef/Puppet/Salt), and HA/immutable infrastructure patterns, and has a track record of moving systems toward repeatable, documented automation so he can focus on bigger problems. At companies including Elastic and Beatport he contributed to large-scale, production-critical systems; he also regularly contributes to open-source projects—from work on the Jujutsu VCS to language repositories like Factor and Exercism—demonstrating both systems- and application-level fluency. Aaron holds a BS with Highest Distinction from Purdue and combines deep UNIX/Linux administration skills with expertise in CI/CD, monitoring, and packaging. An interesting note: he treats automation as a goal to "document himself out of a job," reflecting a pragmatic focus on durable, maintainable infrastructure rather than one-off fixes.
