What’s already been done
Not an abstract “17 years of experience” — concrete tasks and outcomes from real work, with numbers.
RTO cut 3.5x
The problem. The company had backups “for show” — backups were being made, but nobody checked whether they could actually be restored from, and nobody measured how long that would take.
The fix. Rebuilt the backup strategy from scratch: defined RTO/RPO for every critical system, introduced regular test restores — not “a backup exists” but “a backup has been verified.”
The result. Recovery time dropped 3.5x. Every critical system got real RPO tracking, not just tracking on paper.
Capital costs for a typical system — down 80%
The problem. Every new system was deployed on its own physical server — slow, expensive, and harder to maintain as the fleet grew.
The fix. Designed and deployed Hyper-V virtualization, consolidating server roles onto fewer physical hosts with redundancy.
The result. CAPEX for a typical system down 80%, support time down 55%, deployment time down 35%. Fault tolerance up 80% through standardization and redundancy.
Moving to VoIP — a 35% cut in the communications budget
The problem. An outdated PBX on physical lines was expensive to run, and expanding it meant new capital spending.
The fix. Moved telephony onto IP, keeping call quality and functionality unchanged for users.
The result. A 35% cut in the communications budget, with the same call quality.
Mail downtime near zero — even during planned maintenance
The problem. A single mail server was a single point of failure: any maintenance or outage meant mail downtime for the entire company.
The fix. Deployed and maintain a 3-node Microsoft Exchange DAG — with automatic failover between nodes.
The result. Downtime near zero even during planned maintenance — failover between nodes happens without intervention, and users don’t even notice it happening.
