Data Governance & Data Analyst

I make data
trustworthy.
Then usable.

Four years in a Belgian insurance group. Two years as a data steward — data quality, governance, GDPR compliance. Two years as an analyst — data extraction in SAS and Salesforce, KPI data preparation, process automation. Today I coordinate a 15-person process consolidation project and prepare the data that feeds the KPIs.

§ 01 — Perspective

Data comes from somewhere.

I started in a Belgian insurance group as a data steward. For two years the work was the records that wouldn't reconcile — fields that disagreed across systems, customer histories that split in two, cases where the data was technically valid and still wrong. Alongside it: GDPR compliance on customer data, and quarterly data quality audits across business units.

Every figure in a database is the end of a chain. A rule written a decade ago. A market with three players instead of thirty. A person filling in a form who didn't quite understand the question. Data quality work is where those chains become visible, because it is where they break.

Two years as an analyst taught me the other half: pulling the data the business needs — SAS for commission and mass payment runs, Salesforce for customer data — and preparing the datasets that feed the KPIs. That side of the job is about deciding which parts of the context a business can actually act on, and saying so clearly enough that someone can make a decision from it.

A number is never only a number. It is the last step of something that happened in the world.

My current work joins the two. I coordinate a process consolidation project — routines that had never been standardised are pulled into one simple workflow — and I prepare the data that feeds the KPIs. That means framing the requirement with fifteen people from different functions, then holding a data definition firmly enough that a figure means the same thing in one department as in another.

My strength isn't knowing everything in advance. It is finding what needs to be known quickly, understanding the context around it, and turning that into something usable. That is also where slim.lu and Arbitoria come from: I define the problem, the rules and the validation criteria, and direct AI tools to build them.

Insurance Data — Governance & Analytics

Professional · Anonymised case studies · 2022 — present

Four years in a Belgian insurance group, in two parts. As a data steward: data quality across systems, governance, GDPR compliance on customer data, quarterly quality audits across business units. As an analyst: SAS extraction for commission and mass payment runs, customer data extraction from Salesforce, preparing the datasets behind the KPIs, and automating the team's email workflow in Python. Today, coordinating a process consolidation project across fifteen people, together with preparing the data that feeds the KPIs. Specifics anonymised.

slim.lu

Personal · Live · Open source · Belgium · NL/FR/EN

A price comparison service for Belgian consumers. Belgian telecom pricing is fragmented on purpose: promotional windows expire at different times, bundles change the arithmetic, and brand names hide ownership. The service structures that mess into comparable information — mobile, internet and three bundle types, four operators — and publishes what comparison sites keep out of sight: the source and last-checked time per provider, which operators are excluded and why, and how affiliate commissions relate to ranking. I defined the problem, the ranking rules and the validation criteria; the implementation is AI-assisted.

Arbitoria

Personal · Live · Independent publication · KO/EN/FR

An independent multilingual publication about social and technological change. Instead of arguing toward a single conclusion, it takes a possible future as a reference point and re-reads the present against it. Each language version is written from a shared source document rather than translated. Current writing covers the EU digital identity wallet — a regulatory reading that runs directly on from the governance and GDPR work.

Not knowing is no excuse.

The EU digital identity wallet has to be in place by the end of 2026, and most people have never heard of it. The piece argues the working infrastructure was already built by banks and telecoms years ago — eIDAS 2.0 is ratifying what exists rather than creating it.

Family, Item Five.

Member states must make family relationships electronically verifiable through national registers — but the rulebook defining what such a credential actually contains is still missing, with the deadline approaching.

Designed to Forget You.

Europe's age verification reaches privacy by issuing thirty single-use credentials at a time instead of adopting the zero-knowledge schemes cryptographers recommend — moving the cost of privacy from the institution onto the person.

The publication

How Arbitoria works.

Fact and assumption are kept separate in every piece, nothing publishes before its sources clear review, and edits stay visible rather than silent. The method and the disclosure are both written down.

§ 05 — Contact

Let's talk.

I live in Nivelles and I'm available in Belgium and Luxembourg, hybrid at two office days a week. The roles that fit are data governance, data quality, and data analysis and KPI data preparation — work where understanding why the data looks the way it does is part of the job, not a detour from it.

Korean (native), French (professional), English (working knowledge), Dutch (basic). Permanent roles preferred; project work considered.
