Senior🎓
Top SchoolSerge Tkatchouk is a Senior DevOps Engineer based in Larnaca, Cyprus, with over 10 years of hands-on experience in extreme troubleshooting, network operations, and infrastructure automation. At Qrator Labs he has driven Kubernetes and CI/CD adoption, introduced application-level monitoring and tracing, and led conversions of legacy apps to containerized deployments. His background spans NOC engineering, datacenter and ISP-grade networking, and on-call incident response, which gives him a strong bias for reliability and operability. An active open-source contributor, he made notable backend contributions to the Go-based gonic music streaming server—implementing transcoding-aware caching and FFmpeg integration to improve performance. Not actively seeking new roles, he nonetheless continues to explore practical tooling and performance optimizations across cloud-native stacks.
