What I bring to your organization
Services tailored to nonprofits and SMBs: pragmatic, documented, jargon-free. You don't need a full-time IT director: you need a trusted technical partner.
These are quoted after a first conversation about your setup: the price depends on your estate, not on a catalogue. Free quote, no commitment. And if you need the website and the security work together, the packages cover the most common cases.
Security check-up
Review of your setup: weak points, misconfigurations and improvement areas. Clear report with prioritized recommendations.
Systems administration
Management of your Linux/Windows servers, routers and firewalls. Monitoring with Zabbix, updates and rapid response.
Infrastructure hardening
System hardening, network segmentation, access and password management. Solid foundations to reduce your exposure.
Virtualization
Deployment and administration of your on-premise virtualized environments (Proxmox, VMware). Containerization with Docker.
Business continuity
Backup strategy, documented recovery procedures and regular testing. So your activity survives any incident.
Support & guidance
Single technical contact for organizations without an IT department. Regular follow-up, assistance when incidents happen, documentation and team coaching.
Need both at once?
Three packages bundle the website build and the security work into a single quote, for about 10% less than buying them separately, for nonprofits, small businesses and tourism hosts.
Your online presence, hassle-free
Modern, fast and accessible websites, built for nonprofits and SMBs that want a professional showcase without agency costs or delays.
Landing page
A professional one-page or multi-section website. Responsive design, fast loading, contact form. Turnkey delivery.
Multi-page site
Structured site of 3 to 5 pages, no CMS. Ideal for organizations with stable content: about, team, contact.
Design & branding
Brand guidelines, mockups and implementation. A site that reflects you, consistent with your communication.
SEO & performance
Natural search and performance optimization: Core Web Vitals, tags, sitemap. To be found on Google.
Redesign
Modernization of an existing site: new design, technical migration, improved performance and accessibility.
Maintenance
Regular updates, automatic backups, availability monitoring and rapid fixes. Your site in good hands.
The site is yours. Actually yours.
Many cheap offers are rentals: you pay every month, and the day you stop, the site disappears. Here the code is delivered to you under a free licence. You host it where you want, you hand it to whoever you want, and it keeps running even if we stop working together.
No rental
You pay once for the build, not a subscription to stay online. Maintenance is a service, not a toll.
No mandatory provider
The code is standard and documented. Any developer can take over: me included, but not only me.
Nothing to take on trust
The site you are reading is itself published under the AGPL-3.0 licence. You can check how it is built before trusting me with yours.
Clear packages
No surprises. The packages below cover the most common needs, priced in euros and Pacific francs. I work in mainland France as well as French Polynesia. Free quote for any specific project.

How I work
A structured four-phase approach, adapted to your organization's operational reality.
Risk analysis
Mapping of your setup: what's critical to your business, what's exposed, what's missing. Findings prioritized to your business.
Hardening
System hardening, network segmentation, access management, encryption and update policy based on public baselines (CIS).
Continuous monitoring
Monitoring put in place: dashboards, alerts on anomalies and periodic log review.
Incident preparedness
Tested backups, written procedures, a simple plan: who to call, what to unplug, how to restart. An incident is prepared before it happens.
Operational security is not a final state: it's an ongoing process of adapting to threats and to the evolution of your organization.
