About

My Microsoft certifications date from 2008, but I was writing code well before that. Since 2012 I work through my own company, Devchild BV, registered in Ostend. One man, no subcontractors.

Most of my career happened where software meets the physical world: train conductors checking tickets, steel leaving a mill, CNC machines cutting floorboards. That kind of software has to keep working for years, so I build it that way.

Depending on what a client needs I write the code, lead the team, or do both at once. The Scrum Master certificate came in 2016 because somebody had to run the meetings properly.

What I do

.NET development

C#, WebAPI, WPF, Angular on the front when needed, SQL Server or Oracle underneath. I also take on the legacy codebases nobody else wants to touch.

Team lead

Planning, code review, mentoring. I have led teams of seven developers and kept my own commits going at the same time.

Scrum master

Certified since 2016. I keep the sprints short, the retrospectives honest and the meetings few.

Technical leadership

Architecture decisions, code standards, CI/CD pipelines. Explaining to management why the rewrite is, or is not, worth it.
