Summary
🤩
Rockstar🎓
Top SchoolAvishai Ish-shalom is a seasoned engineering leader and hands-on systems architect with 14 years building high-scale, cost-efficient distributed systems and mentoring dev and ops teams. He blends deep Linux/ops expertise—down to implementing container syscalls in an educational rubber-docker repo—with broad software fluency across Java, Scala, Go, Python, Ruby, Clojure and C. As a founder-senior leader (CTO/co-founder of Fewbytes, engineering manager at Wix) he’s equally comfortable shaping strategy and diving into CI/CD, monitoring and automation workstreams. He’s an active community builder and speaker, organizing conferences and volunteering as an instructor for DevOps education. Known jokingly as a “Glorified Janitor” and a sudoer on GitHub, he favors practical, long-lived solutions and teaching teams how to maintain what matters.

A workshop on Linux containers: Rebuild Docker from Scratch
Role in this project:
Back-end Developer & DevOps Engineer
Back-end Developer & DevOps EngineerContributions:88 commits, 12 PRs, 89 pushes in 2 years 3 months
Contributions summary:Avishai contributed significantly to building a containerization workshop by adding system calls to interact with the Linux kernel. They implemented `pivot_root`, `unshare`, `mount`, `umount`, `setns`, `sethostname` and `clone` syscalls, which are core to container creation and management. Further, they added constants related to namespaces and mounting to make syscalls easier to use. The user also added supporting utilities like `mount2` and code to bootstrap images, which further reinforces their role in building and maintaining the infrastructure.
