Rockstar🎓
Top SchoolNir Soffer is a self-taught system programmer and software architect with 16 years of experience, currently working on OpenShift Data Foundation disaster recovery at IBM. He specializes in rescuing and modernizing legacy systems, smashing tricky low-level bugs, and shipping reliable infrastructure across stacks—from C concurrency libraries and CPython internals to Kubernetes drivers and virtualization/storage tools. His open-source footprint includes contributions to high-profile projects such as python/cpython, kubernetes/minikube and libmill, and he helped harden and profile large daemons like vdsm using yappi. At Red Hat he drove major storage improvements (including monitoring speedups by orders of magnitude), co-maintained vdsm, and filed multiple patents in virtualization. Based in Israel, he pairs pragmatic test-driven development with deep systems instincts and a taste for clean, maintainable refactors.
