Freelance .NET developer · Anzegem, Belgium

I make your systems talk to each other.

Back-end integrations, Azure and clean architecture. Like mycelium under a forest floor, I build the quiet network that keeps your CRM, ERP and finance tools in sync, built to stay reliable and secure for years.

What you can hire me for

01

API design & integrations

REST APIs, message brokers and sync platforms connecting Zoho, ERPs, finance tools and whatever else you run.

02

.NET back-end development

C#, ASP.NET Core, Azure Functions and Service Bus. With DDD, CQRS and tests as the default, not an extra.

03

Legacy modernization

Moving ageing .NET Framework code to a modern, maintainable architecture without switching the lights off.

04

Consulting & code audits

A second pair of eyes on your codebase and architecture, with clear reasoning behind every recommendation.

Selected work

Most of my work runs behind client firewalls, so these are told by domain, not by name.

Business software · SaaS

A no-code integration platform

A config-driven Azure platform that lets support teams set up, monitor and tune sync processes between a CRM suite and financial systems. No code required. I launched most of its production integrations and am moving it to a distributed-worker architecture.

Step-up security for sensitive data

Full-stack features for an enterprise app handling sensitive records and physical access control, with Keycloak step-up authentication on critical operations and a fully translated (NL/FR) error pipeline from back-end to front-end.

Re-architecting an order portal

Rebuilt the architecture and data connections of an existing order portal, so it now runs faster, is simpler to maintain, and feels better to use.

Real-time 3D product configurator

A Blazor Server app with an embedded Unity WebGL configurator that validates feasibility live and generates bills of materials and technical drawings, all kept in sync over SignalR.

// 03 — About

From the repair bench to architecture.

Before software I repaired hardware, ran IT operations and worked as a 3D modeller. That route taught me to talk with business people and engineers in the same meeting, and to turn fuzzy requirements into maintainable systems.

Today I care about clean code, domain-driven design and architecture that still makes sense in five years. I work on Fedora, experiment with local LLMs, and recharge outdoors.
