Over the year's I spend a lot of time behind my computer. As a hobby I created several websites. I'm familair with both front end (HTML, CSS and Javascript) and backend development (PHP, MySQL) of websites. I also wanted to learn more about mobile development. So I learned C# and started using Visual Studio from Microsoft. With Xamarin.Forms I created several mobile apps for personal use and fun. My focus was on Android/IOS apps.

Along the way I learned Python. I like the possibilities of use. For example automation of Excel and more recently I started with data science and machinelearning with Python.

This site is my online reference. If you like it, feel free to use it.
