Professional summary

A career built on hands-on engineering, customer projects, homelabs, and real-world problem solving.

I am an experienced system engineer with a strong background in Windows Server, Active Directory, networking, Hyper-V clustering, SAN storage, modern workplace solutions, and O365 migrations. Over the years I’ve worked with environments ranging from small businesses to enterprise-grade infrastructures.

Next to my day job I write down what I build and fix: homelab setups, tutorials and the lessons from real projects, so you can skip the mistakes I already made.

Through Mylemans Online I share guides, scripts, videos and the free learning paths on Mylemans Labs. Mylemans Online is my own side project and is not affiliated with my employer.

How the content here is made

Every guide on this site and every lesson on Mylemans Labs is based on something I built, broke or fixed myself, in my own lab or in my day job, and the videos show the real thing happening. I use AI tools to help with drafting, editing and structuring posts, turning video transcripts into written steps, and checking my writing. I review every command, screenshot and claim before it goes live, and the mistakes you find are mine. Sponsored or gifted products are always labelled as such in the post itself.
