About me

My name is Daniël van Hoesel, people also call me DEE, by the first letter of my name. I'm a freelance full stack developer with over 20 years of professional experience. However, I have been writing code since I built my first computer as a teenager.

I am 37 years old and live in Haarlem, The Netherlands, with my wife and two kids. I am fluent in both Dutch and English.

When I'm not developing software or spending time with my family, I enjoy building furniture and other interior products. My wife and I design and sell these products through her blog interikleur.com.

I really love the challenge of brainstorming, architecting, and developing new products from concept to production solutions. I like to work as lean and agile as possible, while making sure my code is clean, well-tested, and easy to maintain. I deploy often by breaking features down into smaller components to test their viability before investing time in unused ideas.

I prefer to work remotely or in a hybrid setup most of the time.

If you have any questions or if you'd like to chat about a new project, feel free to contact me using my details below.

Tech

These are some of the technologies I've worked with. Some are more recent than others, and my experience with them varies in depth.

I strongly believe that the choice of the technology stack should be based on the project requirements and the environment. Not every problem can be solved with the same approach, sometimes you need different tools to fix specific problems.
