Summary
👤
Senior🎓
Top SchoolSergei Grishin is a backend engineer with 10 years of experience building and operating distributed systems, container platforms, and storage integrations across startups and enterprise environments. Based in Spain, he specializes in Go and has deep hands-on expertise in containerization (Docker/Podman, Kubernetes/K3s), systems architecture, protocol implementation, and infrastructure automation (Ansible, Terraform, Helm). His work spans databases and streaming systems—PostgreSQL/TimescaleDB, ClickHouse, InfluxDB, ElasticSearch, NATS—and includes building a Lambda-like container management system in Go. At Dell EMC he developed a Kubernetes CSI plugin and contributed to custom Kubernetes builds, while at V4Scale he combines DevOps and backend responsibilities to design scalable, production-ready platforms. A curious technologist who enjoys unpacking how things work, he also presents technical topics publicly and pursues continuous learning (including English and sports-related interests) outside of coding.
