Odysseas Lampros
Katsifos
IT Systems Engineer with a strong focus on infrastructure reliability, virtualisation, and automation. Hands-on experience building and operating production environments — from designing a 3-node Proxmox VE cluster with Ceph RBD-backed storage on an HPE C7000 BladeSystem, to gradually migrating a full production homelab from Greece to Ireland with a new storage architecture and zero data loss. Equally comfortable in a professional IT role and running self-managed systems, with a practical approach to monitoring, security, and keeping things running.
About Me
My interest in infrastructure started well before it became a job. It started in Greece with Homelab v1 — consumer hardware, a lot of trial and error, and every service self-hosted from scratch. That's where I learned Proxmox, Ceph, and Docker, and what production-grade reliability actually means.
When I relocated to Ireland, v1 became unreachable for months. Instead of waiting, I sourced an HPE C7000 BladeSystem from the UK and built Homelab v2 from the ground up with a new Ceph RBD storage architecture. Services were migrated one by one over ~2,700 km until v1 was cleanly retired late 2025.
I take full responsibility of the systems I work on. Whether that means planning a migration, setting up monitoring from scratch, responding to an incident at an odd hour, or documenting recovery procedures so nothing is left to memory — I treat infrastructure as something worth caring about, not just maintaining.
I work well independently and within teams, and I'm most comfortable in environments where reliability and security are taken seriously. Currently based in County Clare, Ireland and actively looking for a role where I can keep growing and contribute to infrastructure that matters.
Professional Experience
- Supported and maintained production IT systems in a mixed on-premises environment, handling incidents and service requests.
- Owned the deployment and operation of monitoring and alerting systems, improving visibility and reducing incident resolution time.
- Reduced support ticket reopen rates through improved workflows and effective use of the Zammad ticketing system.
- Deployed and maintained containerised services using Docker to provide stable, dependency-isolated environments.
- Planned and executed migrations to Proxmox VE and Proxmox Backup Server with minimal service disruption.
- Improved operational security by implementing secure credential sharing and access controls.
Infrastructure Projects
- Built around an HPE C7000 BladeSystem — blades were brought up one by one as the new foundation for v2.
- Designed a new storage architecture using Ceph RBD as the primary block storage backend for all Proxmox VE workloads.
- Gradually migrated all services from the Greece v1 setup (~2,700 km) with no data loss — v1 was taken offline late 2025 when the last service migrated.
- Operates 20+ containerised services including identity, media, monitoring, messaging, and storage workloads using Docker Compose.
- Built centralised notification pipelines for system health, maintenance reporting, and failure detection.
- Original homelab — where the fundamentals were built: Proxmox VE, Docker Compose, and ZFS storage from scratch.
- Hosted core personal services including mail, identity (SSO), monitoring, media, and a ticketing system.
- Became unreachable for extended periods during relocation — accelerated the decision to build v2 and migrate everything across.
- Taken offline late 2025 after the last service was successfully migrated to v2, with all data and configurations preserved.
