About me
I'm an IT and cybersecurity professional with over 20 years of experience. I started as a systems administrator in 2002 and made the full jump to cybersecurity in 2012. Since then, I've built defensive infrastructure at scale — including 8 years supporting the European Commission — focused on threat detection engineering, SIEM and Splunk.
In 2018 I founded Check4Cyber, my own boutique consultancy in Luxembourg. From there I deliver detection engineering, audits and cloud migration to organizations that need more depth than an off-the-shelf service.
Over the last few years, AI has become my technical obsession. Not a formal job — it's the tool I use to build LUCRITAS, LiquiWatch, SIMB and AETHERIA. Neural reasoning, automation, LLM-assisted engineering. I believe the future of digital defense flows through here.
