Top SchoolFerenc Erki is an independent IT advisor and performance consultant with 15 years of hands-on experience building and optimizing high-performance infrastructure, automation, and observability platforms. Based in Berlin, he has a strong open-source pedigree as maintainer of Rex and contributor to projects like Elasticsearch Curator, bringing practical DevOps tooling expertise across Gentoo, Perl, PostgreSQL and embedded Linux via OpenWrt work. He helps organizations cut infrastructure TCO dramatically while speeding provisioning and CI/CD — recent engagements report up to 75% complexity reduction, 60x lower build resource usage, and 10x faster provisioning.
