Core expertise
Six areas, from networking to training. Each one links to what backs it up: projects, articles, tools and cheatsheets.
Networks & Systems
Windows Server (Active Directory, file server, DNS, DHCP, remote desktop, MDT and WDS to image PCs) and Linux. LAN/WLAN networks, VPN, FTP/SFTP. A homelab lets me test configurations and services before deploying them.
IT Security
Stormshield SNS firewalls, VPN, identity security on Microsoft 365 and Google Workspace, email authentication (SPF, DKIM, DMARC).
Messaging & Cloud
Setting up and administering Microsoft 365 and Google Workspace (with GAM, on the command line) day to day: migrations from IMAP (OVH, Gandi, IONOS, Orange…), Gmail and Outlook, SMTP analysis, deliverability, DNS zones (MX, SPF, DKIM, DMARC) and operational maintenance.
Projects
Articles
AI, Google Workspace, M365 & GDPR training
I train and support users in artificial intelligence, Google Workspace, Microsoft 365 and GDPR best practices. This support extends day-to-day helpdesk work: getting started with the tools and answering users' questions.
Development & Automation
Website creation and management (WordPress, Wix, Shopify, Weebly, PrestaShop, React). Scripts and tools in C#, Java, Python, PowerShell, Bash, SQL and PHP. University projects in Java, SDL2 and Angular, and a Minecraft plugin in Java: the repositories are on GitHub.
