About Me

Web developer based in Liège, Belgium. I enjoy designing and building systems end-to-end, from data pipelines and APIs to polished user interfaces. Most of my projects come from a real frustration or a concrete problem to solve, like BizComp, a business intelligence platform built on official Belgian data, recognized by the Belgian open data initiative.

What I Build

The kinds of systems I enjoy building the most.

Data Pipelines

Ingestion, transformation, and structuring of raw data — public registries, third-party APIs, XBRL or PDF files — into queryable databases.

APIs & Backend Systems

Server architectures with service orchestration, queues, real-time streaming, and AI integration — designed for reliability and scale.

User Interfaces

Interactive web applications with dashboards, data visualizations, and polished UX — connected to the systems I build.

BizComp Intelligence

Recognized by the Belgian open data initiative

BizComp was born from a simple observation: Belgian public company data is rich but scattered and hard to access. I signed a data agreement with the BCE, ingested the full KBO registry, and built an AI agent that answers questions about any active Belgian company in French, English, and Dutch. Submitted for official recognition by the Belgian open data initiative. Available at bizcomp.be.

Mediplan

Mediplan is a comprehensive web application designed to streamline medical appointment booking. Patients can easily filter doctors by specialty, view available slots on an interactive calendar, and confirm their appointments in just a few clicks. Practitioners have a dedicated dashboard to manage their schedules and view upcoming consultations, while an admin panel provides oversight for user registration and key platform statistics.
