Summary
👤
Senior🎓
Top SchoolSergey Linnik is a pragmatic engineering leader with 15 years of experience building and operating high-throughput backend systems, currently leading a team at VK Cloud focused on reliable, fast replication from Tarantool to DWH. He combines deep hands-on knowledge of languages and databases—Go, PHP, SQL, Redis, PostgreSQL—with architecture and developer-productivity work that cuts delivery time through automation and tooling. Sergey has led cross-functional teams at X5 Digital and RetailCRM, architecting new services and building internal developer tools while contributing low-level C extensions where performance mattered. He prefers simple solutions to hard problems, avoids JVM ecosystems, and enjoys taking on infrastructure and data-delivery challenges. An active contributor to open-source (notably fixes and enhancements in the long-running tvheadend project), he brings practical expertise in Kafka, GraphQL, Docker/Kubernetes, Terraform and cloud storage. Based in Voronezh, he pairs academic rigor (diploma with honors) with a bias for production-ready reliability.
