I’ve gained much experience working with clients in Belgium, the Netherlands, France and Singapore during the last ten years. It’s allowed me to become an expert in my field and to take away important lessons from every project!

It’s incredibly informative to work with a variety of clients and companies. Especially when it comes to safety and quality, over time I’ve been able to put together best practices in our field. No two days are the same and I really enjoy that challenge.
