Back to original languageAbout Kevin
I am in a cybersecurity master's program, doing an apprenticeship as an Assistant CIO in an industrial SME. My daily job is to fix IT systems that have been running without anyone in charge for a long time. And that's exactly what I offer here, on the side, to small businesses that have the same problem.
What I've built in recent months, to give you a concrete idea:
- Complete overhaul of a Wi-Fi network that relied on a single shared password circulating among visitors and former employees. Three separate networks afterwards, authentication by device, no more stray keys. A hacked terminal no longer affects servers.
- Deployment of EDR protection on 45 workstations, with a single console to see in real-time what's happening on the network.
- A map of the IT system that updates itself via PowerShell scripts. No more half-wrong Excel files that no one maintains anymore.
- Dynamic display in the reception hall, built entirely on Microsoft tools already paid for by the company. Zero additional licenses, one-click publication approval by management.
- The missing GDPR documentation, and an IT charter dating back to 2013 updated (generative AI, remote work, BYOD).
My technical skills: networking (CCNA and Stormshield certified), Windows and Active Directory administration, Microsoft 365, Linux hardening, and a lot of automation in Python and PowerShell. I also code custom tools.
How I work: I audit the existing system, I define with you what we aim for, I deliver in stages, and I document everything so that you are not dependent on me after I leave. I prefer a clear fixed price for a specific deliverable rather than hourly billing that says nothing about the result.
I work remotely, in the evenings and on weekends. For small tasks, that's more than enough. For the rest, let's talk about it.
