Independent Senior Data Engineer & Architect — Luxembourg 🇱🇺
20 years designing and operating data platforms across regulated industries. I build things that process millions of records daily, survive production incidents at 2 AM, and are still maintainable by the next engineer.
Currently available for freelance missions — remote or Luxembourg-based.
I design cloud-native data platforms end-to-end — from source integration to consumption layer. Production-proven numbers:
- 40 million data points ingested daily with 99.9% uptime
- 200+ SAP tables replicated via CDC (SCD Type 2)
- 1,000+ data pipelines delivered across 14 countries
- Multi-source integration: databases, APIs, SFTP, file systems, ERPs
- Medallion architecture (Bronze/Silver/Gold) with automated data quality gates
Whether you need a platform built from scratch, a migration executed without downtime, or an existing architecture audited and optimized — that's what I do.

Regulated industries where data quality, governance, and reliability aren't optional — they're compliance. That's where I've built my career, and that's the standard I bring to every project.
Based in Luxembourg. Father of two. When I'm not wrangling data, I'm probably playing World of Warcraft Classic or dying in Elden Ring.
I value pragmatic solutions over complex architectures, and I'm not afraid to challenge technology hype when simpler approaches work better.
Open to freelance missions — data platform design, data contract implementation, architecture audit, cloud migration, pipeline engineering.
