I’m Martien de Kleijn, a freelance IT consultant from Rotterdam with a practical, no-nonsense approach: get things done, deliver real value, and keep businesses moving. With over 15 years of experience across healthcare, finance, government, logistics, and energy, I thrive on solving complex IT challenges and making sure projects actually finish—on time and to spec.
My core strengths? Taking ownership, troubleshooting stubborn issues, and driving technical projects over the finish line. Whether it’s major migrations, infrastructure upgrades, or automating daily routines, I focus on practical solutions that work—using tools like PowerShell, SCCM, and cloud platforms to keep IT reliable and efficient. Clients know me for my clear communication, hands-on mentality, and ability to step in wherever I’m needed.
I enjoy building solutions that make life easier for both IT teams and end users, mentoring colleagues, and streamlining everyday operations. From greenfield deployments to firefighting emergencies, I don’t shy away from tough jobs.
Outside of IT, I’m passionate about music, concerts, and festivals, but you’ll also find me working on home and garden projects—or off on a camping adventure with my family in our camper, exploring new places and making memories along the way. I love practical solutions, new technology, and turning complex challenges into something simple and workable.
Looking for someone who rolls up their sleeves and gets IT sorted? Let’s connect—I’m open for freelance projects, interim roles, or just a chat about smart solutions.
