Data governance and data analyst with nearly four years in Belgian insurance. Two years as a data steward on MDM record matching and merging; two years running the monthly data cycle behind non-life reporting — extracting claims and premium data with SAS, loading it into Salesforce in bulk, and validating the figures that set broker commission tiers. What interests me is where a number comes from, which rule shaped it and who is accountable for it. The same instinct drives slim.lu, where opaque market pricing becomes a transparent comparison, and Arbitoria, where I write about social and technological change.
- Own the monthly close cycle for non-life reporting: around 150 Power BI dashboards reset at the start of each month and must be brought back to green. Two thirds of the chain runs automatically; when a step fails I escalate to IT, then check what is ready and run the rest.
- Extract claims and premium data with SAS, prepare the files and load them into Salesforce in bulk with Data Loader, then trigger the loss-ratio computation through Jira once both sides are validated. That ratio sets broker commission tiers, so a wrong field means a wrong payment, not a wrong chart.
- Coordinate a process consolidation project across a 15-person cross-functional team: standardising procedures into a single workflow and preparing the data behind the KPIs.
- Reconcile broker contracts against the CRM, check broker and agent conditions, handle data-maintenance requests from the claims platform, and automate the team's mail routing in Python.
- MDM record matching and merging on customer data: deciding which record takes priority, which fields carry over, and when a merge must not happen.
- Managed data quality across organisational databases, ensuring GDPR compliance and integrity for customer records.
- Conducted quarterly data quality audits across multiple business units, identifying and resolving integrity issues.
- Worked with IT and business teams to reconcile data across systems and standardise validation rules.
- Front desk operations, guest relations and F&B service.
- Floor service in a Korean restaurant in Brussels, in daily contact with customers. Over the first six months of the period, also taught a weekly two-hour Korean class at a youth centre (Schaerbeek) and gave private lessons: a syllabus of my own — grammar, syntax and expression, taught through role-play and video material.
Belgian consumer price comparison service, in active development and operation — an analyst’s observation about opaque pricing turned into a tool people can decide with. Structures fragmented operator pricing into comparable information across mobile, internet and three bundle types, currently covering four Belgian operators. Prices are collected and validated automatically on a daily schedule. The service publishes what comparison sites usually keep out of sight: the source and last-checked time for each provider, which operators are excluded and the reason for each, and how affiliate commissions relate to ranking. Trilingual product (NL/FR/EN) built on Next.js and TypeScript. Open source.
Independent multilingual publication (KO/EN/FR). 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. My role covers the writing, editorial direction and information architecture, the source-verification process — fact and assumption are kept separate in every piece, and nothing publishes until its sources have been reviewed — and building the service itself. Where slim.lu helps people compare and decide, Arbitoria is where the thinking and interpretation go.
