Top SchoolErik Dalén is a Site Reliability Engineer with 13+ years building and automating Linux-backed infrastructure for large-scale services, currently at Resolution Games and maintaining the Return of Reckoning server project. He blends deep configuration management and DevOps expertise—Puppet, Consul, containerized AWS stacks—with hands-on coding in Ruby, Python, JavaScript, C# and C. At companies like GitHub, Spotify and Fishbrain he led migrations, on-call processes, hardware provisioning and containerization efforts while mentoring teams. An active open-source contributor, he has improved type definitions in DefinitelyTyped and enhanced SAML-to-AWS tooling, and speaks regularly at industry conferences. Unusually, he combines commercial SRE rigor with long-term hobbyist reverse-engineering experience from MMORPG server development, giving him a uniquely broad systems perspective.
