Sami Haahtinen is a Site Reliability Engineer with around 17–20 years of hands-on experience designing, operating and securing mixed Linux, Windows and Unix server estates and customer networks. He built and ran his own consultancy before moving into technical specialist and service engineering roles, and now focuses on reliability at Google where he applies deep protocol and systems knowledge to large-scale cloud platforms. Sami is comfortable across the stack—from low-level networking and routing to containerized microservices and infrastructure-as-code—and has a knack for translating complex technical issues into clear explanations for non-technical stakeholders. His background running an ISP-grade hosting platform and creating custom automation tools gives him a pragmatic, security-minded approach to performance and operability. Colleagues know him for combining broad infrastructure experience with a craftsman’s attention to durable, debuggable solutions.
