ABOUT ME
Senior Backend Developer with 5+ years of experience
Senior Backend Developer with 5+ years of experience
A lot of software engineers face the challenges and complexity of messy code every day. Messy code slows down development and increases the chance for mistakes and gives bugs places to hide. Working in an environment with a lot of messy code has a negative impact on your job satisfaction as it increases your stress level and fear of making changes.
I am passionate about writing clean, readable and maintainable code. I would love to teach you the steps you can take to improve the readability and robustness of your code. I have experience in Domain Driven Design and Test Driven Development. Kotlin is my favourite language, because it is very expressive and clean by design.
Feel free to get in touch if you need help improving your code in Kotlin or Java.

I have a lot of experience working on projects in the Java ecosystem from Java 6 to Java 14. While Java is doing a good job in making the language more modern, it also comes with a lot of unneeded verbosity. That's why I prefer writing new projects in the Kotlin.

Worked on a Saas product that made heavy use of postgres. I have a lot of experience in mapping business logic to an Anemic database model and I also explored a lot of ways to overcome the problems that an Anemic model yields using event based solutions.

Object Orientation is a good way to encapsulation complex logic into small and smart components. In my years of software development I used Object Orientation as a tool to tackle complex problems in game development and building SaaS applications

I use the Functional programming functionality of Kotlin on a Daily basis in my projects. With Functional programming it is easier to express what needs to be done, instead how to do it. This in turn results in more predictable software.

I am an event host at Weerwolven van Nijmegen. Because of the Corona pandemic it became harder to host game nights in person to player Social Deducation games like Werewolves, Mafia or Avalon. To still be able to play together I build a Discord bot that makes it possible to play Werewolves on Discord. The Werewolves Discord bot relieves the Moderator in most tasks, so even players who are not familiar with the game can moderator.
