20 years of building and maintaining critical systems in private banking have taught me one thing: technical debt is never just a symptom—it's business knowledge fossilized in code. It's not solved by rewriting, but by unearthing it.

Today, as Chapter Lead Tech in Luxembourg, I manage 18 Tech Leads across 4 squads, 30+ applications, and a multi-technology data platform (S3, Dremio, Snowflake, Oracle, PostgreSQL).

I am currently specializing in decommissioning a monolith of 230 applications tied to the same database. To achieve this, I am leveraging generative AI to map business rules buried in the code.

As an independent consultant, I assist IT teams looking to modernize their legacy systems. My approach uses AI as a lever at each critical stage:

— Discovery: identifying real functional areas and 'forgotten' existing components—business rules no one documents but the system depends on

— Mapping: automatically reconstructing what the code actually does, beyond what the documentation claims

— Reconstruction: proposing a target architecture based on what actually exists, not on assumptions

My approach is pragmatic, forged by years in regulated environments where errors are costly.

I don't sell "digital transformation"—I help you understand what you have before deciding what to do with it.
