Summary

I am a self-employed backend developer with 5 years of experience in international teams. Because I place a high value on good communication and collaboration, I can quickly get up to speed in new teams and coach new teammates in a short time.

One of my passions is learning. That allows me to become productive very quickly, even when the technology is new to me. Often it took less than 3 days from researching a new library to implementing new features.

I appreciate clean code and automated testing (with TDD). This way, I can write code that is easy to understand and maintain, and still in use many years later.
