ABOUT ME

  • I have been building software for close to 20 years. I started with PHP and switched to .NET back in 2006 (1.1), and since then most of my work has been around enterprise applications, ERP satellite processes, integrations and, in the last years, cloud-native platforms on Azure.
  • I like working close to the business, not only the code: deciding which problems are worth solving, which results are reliable, and how to turn a business need into an architecture that holds up in production. Friendly and pragmatic when leading a team or a project.
  • Outside of work my big passion is racing radio-control cars at national and European level. What I enjoy is exactly the same thing I enjoy at work: tuning something to perform at its best under changing conditions. It keeps the balance between the computer and being outdoors.
