Chlebek.

I build, migrate and secure the infrastructure businesses depend on.

Nearly three decades across Microsoft, VMware, Cisco, networking and Linux — turning complex estates into systems that are simple, secure and stay up. These days that includes Copilot, OpenAI and other AI tools, used daily for scripting, documentation and analysis.

01 — Profile

Nearly three decades of keeping IT running.

The short version

I've worked in IT since 1997 — through the shift from on-premises everything to hybrid and cloud, and the security wake-up calls that came with it. That means I've seen which shortcuts survive production and which ones become next year's outage.

Today my work is mostly Microsoft: migrating Exchange, consolidating Microsoft 365 tenants and directories, moving Active Directory domains with ADMT and Quest tools, and giving people secure remote access. Around that sits the rest of the estate — VMware, Cisco networks, Linux servers and PowerShell in Visual Studio Code to hold it all together, with Copilot, OpenAI and other AI providers now part of daily work.

01

Understand first

Map the dependencies and agree the rollback before touching production.

02

Migrate cleanly

Rehearsed cutovers, clear communication and verified results — no drama.

03

Leave it documented

Secure, monitored systems that are easy to support and hand over.

02 — Experience

Architecting what comes next.

05 — Beyond work

Curious by default.

Off the clock

The best engineers are interested in more than servers. These are the things that recharge me.

Scuba diving

Calm under pressure, at any depth.

Hiking

Long trails and time to think.

Photography

Noticing the details others walk past.

Coding

Small tools built for the fun of it.

New technology

Always testing what comes next.
