Senior🎓
Top SchoolSergey Moiseev is a seasoned software leader and company owner based in Estonia with 29 years in IT and 14 years of professional development experience across startups, agencies, and enterprise projects. He specializes in full-stack Ruby on Rails and JavaScript ecosystems, cloud-native deployments (AWS, Kubernetes, Helm) and migrating legacy systems to modern architectures while balancing DevOps and product needs. Sergey has repeatedly built and led small to mid-size engineering teams, driven complete rewrites and production launches, and introduced agile practices and tooling (Jira/Confluence) to improve delivery. He combines hands-on coding with system architecture, UI and business-process design, and is comfortable working as a contractor via Toptal or running his own firm. A practical technologist, he often acts as the bridge between legacy codebases and new workflows—wrapping old systems to enable incremental modernization without disrupting operations.
