Examples of work in the wild
A small sample of recent and representative work. Client names are omitted here for privacy, though references are available where appropriate.
Three-node Proxmox cluster for core business systems
Problem: Client was running key workloads on a single aging virtualization host with no failover.
What I did: Designed and implemented a three-node Proxmox cluster with shared NFS storage, Proxmox Backup Server, and standard templates. Migrated workloads with minimal downtime.
Result: Hardware failures became inconvenient rather than catastrophic. The client gained clearer capacity planning and a documented recovery process.
- Proxmox VE
- Proxmox Backup Server
- Synology NAS
Modernizing identity and collaboration for a professional services firm
Problem: Mix of on-premises services and ad-hoc cloud usage, weak identity controls, and noisy email security.
What I did: Consolidated users into Microsoft 365, set up Entra-based identity, improved mail hygiene, and implemented sensible security baselines.
Result: Users gained predictable access and the firm reduced support noise around accounts and mail delivery. Leadership gained a clearer picture of risk.
- Microsoft 365
- Entra ID
- Exchange Online
Firewall and VPN redesign with OPNsense
Problem: Flat network, aging firewall, and unreliable remote access. Too much trust in too few controls.
What I did: Implemented OPNsense, created separate networks for key workloads, and deployed VPN access for staff with improved logging and alerting.
Result: Reduced blast radius for incidents and far fewer issues with remote staff connectivity.
- OPNsense
- Site-to-site VPN
- Network segmentation
Backup and recovery you can test, not just hope for
Problem: Backups existed, at least according to the software. Nobody had attempted a full restore in years.
What I did: Standardized backup jobs using Proxmox Backup Server and other tools, created restore runbooks, and ran regular test restores with the operations team.
Result: Leadership gained confidence that data could be recovered. The team understood how to execute under pressure.
- Proxmox Backup Server
- Offsite storage
- Runbooks and testing
If you are facing similar challenges, we can adapt these approaches to your environment rather than starting from theory.
