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.
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.
Fractional Infrastructure
Ongoing senior infrastructure responsibility on a part-time basis.
Consulting
Architecture, troubleshooting, technical decisions and infrastructure reviews.
Project Work
Focused design, implementation, migration or infrastructure improvement projects.
Let's talk infrastructure.
