Zabbix Certified Professional (ZCP) and Specialist (ZCS) | 15 years in production monitoring.
Your Zabbix or Centreon has been in place for years, but alerts are all over the place and nobody has time to fix it?
Or conversely, you're starting an observability project and want to do it right from the start, without inheriting a patched-together platform in 3 years?
That's exactly where I come in.
15 years in production monitoring, mainly in banking/finance and IT service companies/integrators. I've seen clean platforms, messy ones, painful migrations, and POCs that end up in production without us realizing it. My approach: concrete, maintainable, and technical choices that can be justified 3 years later.
🔧 Zabbix & Centreon, the solid foundation
- Full deployment from scratch (distributed architecture, HA, sizing, AD/LDAP integration, ITSM)
- Audit and redesign of an existing platform: cleaning up templates, rationalizing hosts, redesigning alerting
- Major migration and upgrades without breaking the existing system
- Strategic consulting on observability and event correlation
⚙️ n8n, automation for ops
- Enriched alerting (context, criticality, linked runbook, intelligent escalation)
- Self-remediation for recurring incidents
- Integration with your stack (ITSM, CI/CD, SaaS, internal APIs)
🤖 AI applied to observability, my real differentiator
- Incident resolution suggestions via RAG on your documentation and ticket history
- Automatic alert classification and prioritization
- No POCs gathering dust: direct integration into your existing monitoring
I intervene at all stages: pre-sales, scoping, piloting, execution, go-live, skills transfer.
Mission formats: short (audit, scoping, POC) or long (redesign, AIOps integration).
