Custom software,
built by one steady partner.

Omgeving.net

The software package Flemish local authorities use to manage their territorial affairs: environmental permits, enforcement, supervision and housing policy, with an integrated GIS and mapping environment for the civil servant and the citizen alike. More than 200 municipalities work with it. Under the bonnet it is a monolith of 120+ projects and hundreds of thousands of files, built by several subteams.

I helped set Omgeving.net up and came back to it years later, now as lead of a subteam. Besides building, I guide colleagues in working with AI — Claude Code in particular — so the whole team keeps up. One subteam had been stuck for months without delivering anything; I steered it towards a different way of working, which took a few frank conversations, but it is delivering again.

• C#
• WPF
• .NET 10
• CoreWCF
• ASP.NET Core APIs

Central services

The same functional requirements kept recurring project after project: document generation, file management, email sending, minutes management, digital signing and communication with the National Register (Rijksregister), Connective and MAGDA. We centralised them so every application could plug them in and bug fixes happened in one place. Developing, maintaining and handing over those services became my primary task.

• C#
• .NET 6
• Entity Framework Core
• MediatR
• RabbitMQ
• MassTransit
• Angular 10-16
• MS SQL
• Azure DevOps
• Scrum

Citizen

The replacement for Bevolking.NET, with which governments manage their citizens’ data: registering newborns with the National Register (Rijksregister), driving licences, changes of domicile and the police investigations around a new address. Our task was to migrate from AS400 to SQL and to replace the outdated WPF application with a new website.

• C#
• VB.NET
• AS400 → MS SQL 2019
• Entity Framework Core
• ASP.NET Core
• Angular 16
• Playwright
• Azure DevOps

Identity Provider

An authentication service that validated a wide range of clients for an equally wide range of APIs, with a management website around it. Optionally coupled to Gebruikersbeheer, so that roles came along in the claims of the JWT token. Signing in was possible with a username, Windows logon, Azure AD or ItsMe via CSAM — on the intranet as well as on the internet.

• C#
• .NET 6
• IdentityServer 4-6
• ASP.NET Core MVC
• Azure AD
• ItsMe / CSAM

National Register consultation

A multi-tenant application with which users perform all kinds of look-ups in the National Register (Rijksregister). Unlike the intranet solutions Remmicom usually delivers, this one runs on the open internet — with everything that brings in terms of security and isolation.

• C#
• .NET 6
• multi-tenant
• ASP.NET Core
• Angular 16
• Playwright

Link-Octopus

A link between the bookkeeping packages of Remmicom’s various subsidiaries and Octopus. One side spoke AS400 (contracten.net), the other an OData endpoint (ionBIZ) — both are retrieved and synchronised. Still running.

• C#
• .NET Core 3.1
• IBM DB2 iSeries
• AS400
• OData
• Azure DevOps

Central Angular packages

As more Angular applications came along, the need for reusable components grew. We built NPM packages that work both together and separately, with a demo application as a guide alongside them — so colleagues could use them without needing me.

• Angular 16
• RxJS
• Kendo UI
• self-contained components
• NPM
