Infrastructure Consulting

Infrastructure that holds up
under real load.

Network design, cloud migration, and systems engineering for growing companies — built by someone who's run production infrastructure for 25 years, not just diagrammed it on a whiteboard.

Four disciplines, one engineer who's done all of them.

No account managers, no offshore delivery team. The person who scopes the work is the person who builds it.

L2 / L3

Network Design & Implementation

Switching, routing, and firewall architecture built for real growth — not just what fits this year's budget. Juniper, and everything it needs to talk to.

K8S

Cloud & Kubernetes Migration

Move off aging on-prem hardware without the downtime horror stories. GCP and container platforms, migrated by someone who's done it in production, not just in a lab.

3-2-1

Storage & Backup Architecture

Storage that survives hardware failure, and backups you can actually restore from. SAN replication, disaster recovery, and cloud archive tiers.

AD / DNS

Systems & Identity

Active Directory, DNS, DHCP, and hybrid identity — the unglamorous infrastructure every other system quietly depends on to keep working.

About

Built by someone who's carried the pager.

Smart Design Networks is Sergey Mkrtumov — a systems and network engineer who has spent two decades building the infrastructure other companies depend on without ever thinking about it.

From managing a 500-server datacenter to leading a full on-premises-to-cloud modernization for a national manufacturer, the work has always come down to the same three things: make it reliable, make it scale, and be the one who shows up when it breaks.

That's the difference between hiring a consultancy and hiring an engineer. Smart Design Networks is the second one.

GROWTH

Design for the size you're growing into

Undersized infrastructure becomes a rebuild project. Every design accounts for where you'll actually be in three years, not just where you are today.

CLARITY

No black boxes

You get documented configs, real network diagrams, and a system your own team can operate — not a dependency on the consultant forever.

UPTIME

Uptime is the whole job

Migrations happen on your schedule, with rollback plans, because the goal is nobody notices the change happened at all.
