Independent IT Infrastructure Engineering

Infrastructure that works.

Ivan Šećerov, PhD · Senior IT Infrastructure Engineer

More than 20 years of hands-on experience designing, implementing, operating and troubleshooting production infrastructure, with a strong focus on Linux, networking, virtualization and reliability.

Expertise

End-to-end infrastructure work, from architecture and implementation to production operations and problem solving.

Linux & Unix

Production Linux systems, Unix-like environments, services, troubleshooting and systems-level administration.

Virtualization

KVM, Proxmox and VMware, including complete infrastructure environments designed and implemented from the ground up.

Networking

TCP/IP, routing, switching, VLANs, DNS, DHCP, VPN, firewalls, Cisco and network services.

Production Infrastructure

Monitoring, storage, authentication, backup, disaster recovery, reliability and operational troubleshooting.

Architecture & Implementation

Infrastructure design, deployment models, technical requirements, implementation and service delivery.

Infrastructure Improvement

Simplification, performance, reliability and maintainability — with a practical preference for clear, robust solutions.

Approach

Senior technical ownership rather than isolated task execution. The goal is to understand the system, solve the actual problem and leave behind infrastructure that can be operated and maintained.

Design → Implement → Operate → Improve
Work directly with technical teams and decision-makers, taking responsibility for the infrastructure problem rather than adding unnecessary layers, dependencies or process overhead.

Engagement

Remote and flexible engagements for organizations that need experienced infrastructure expertise without necessarily requiring a full-time position.
