Ryan Hansohn is a Senior SRE with 11 years of hands-on cloud and infrastructure experience and a 19-year passion for taking systems apart to understand how they work. He specializes in building, automating, and migrating Big Data ecosystems and has led cloud infrastructure teams at 23andMe before joining Sony Interactive Entertainment. His background spans petabyte-scale Hadoop clusters, Airflow/Spark data pipelines, CI/CD transformations, hybrid cloud architectures, and production observability stacks. Ryan is comfortable owning end-to-end reliability and compliance in highly regulated domains such as healthcare and finance, where he designed PCI- and healthcare-compliant solutions. Known for being the early infrastructure hire who scales systems from a handful of machines to hundreds, he pairs pragmatic operational judgment with deep systems troubleshooting. Based in California, he blends SRE rigor with a tinkerer’s curiosity that surfaces optimizations others miss.
