Cosimo Streppone is a Senior Site Reliability Engineer based in Oslo with 24 years of experience designing, operating and optimizing 24×7 web systems at scale. He combines deep hands-on expertise in backend development, performance tuning and infrastructure (Java, Couchbase, ElasticSearch, Postgres, Varnish, AWS) with proven SRE practices to reduce resource usage and improve reliability. At Kahoot! he rebuilt core game-server components to halve code size and cut average AWS resource consumption by ~50%, and he has driven large-scale recommendation and search improvements across prior roles. At Opera he architected GeoDNS, an OAuth provider and a Puppet-driven config management fleet serving millions of users and 100M+ daily impressions, and even developed an experimental text-clustering algorithm (AGT) that outperformed industry alternatives for multilingual news. A long-time open-source contributor and conference speaker, he prefers prototyping to validate ideas quickly and embraces chaotic production problems as opportunities to learn and fix things.
