Summary
👤
SeniorJohan Andersson is a seasoned technology leader and co-founder serving as CTO at Severalnines with 14 years of experience designing and operating mission-critical web and telco systems. He specializes in architecting fast, highly available platforms that scale to hundreds of millions of users using clustered databases and NoSQL technologies such as MySQL Cluster, Galera, and MongoDB. Johan blends hands-on engineering with strategic product thinking, guiding teams through complex distributed systems, failover, and performance optimization. Based in the Greater Stockholm area, he has a track record of turning demanding uptime and throughput requirements into pragmatic, maintainable architectures.
