Database Administrator @ Multifonds Luxembourg

Engineer focused on the layers that hold systems together — databases, networks, virtualization. Database Administrator by day, homelab operator and security student by night.

In 2025 I completed the full Oracle Cloud Infrastructure certification track — Architect, Foundations, AI, Generative AI, Data Platform and AI Vector Search. Currently enrolled in Cybersecurity Essentials at LLLC · Chambre de Commerce Luxembourg, and maintainer of Snort Vision, an open-source visualization layer for Snort IDS alerts.

I lean open-source first, automate what I touch twice, and treat reliability and security as defaults — not features.

Snort Vision

Real-time visualization layer for Snort IDS alerts

My open-source project that turns raw Snort intrusion detection alerts into a readable, real-time dashboard. Built to make signature-based detection actually useful for small teams and homelab operators.

field work

Built in my own homelab — a hyperconverged platform running Proxmox + Ceph, local LLMs, and a full observability and security stack. The screen shows it being upgraded live.

Homelab Build

Proxmox + Ceph · Local LLM · Wazuh · Zabbix

My personal hyperconverged platform: a Proxmox cluster backed by Ceph distributed storage, running a self-hosted Qwen3 Coder LLM for private code assistance.

Hardened and observed end-to-end — Wazuh for log analysis, file-integrity monitoring and security alerts; Zabbix for hosts, services and Ceph health metrics. The video captures a live node upgrade with zero service downtime.

I'm a cybersecurity enthusiast, not a paid pentester — currently studying Cybersecurity Essentials at LLLC · Chambre de Commerce Luxembourg. Here's the toolkit I run in my homelab and on my own infrastructure.
