Hello, it's me! Codechef!Codechef Logo

I also call myself the CODECHEF

I would describe myself as an independent and entrepreneurial programmer who dares to push boundaries and embraces big challenges. After working as a freelance all-round web developer for several years, I have exclusively focused on specialized front-end/javascript development since 2014. Over the past years, I have gained extensive experience with important front-end frameworks/technologies such as React, Angular, TypeScript, NodeJS, HTML5, and CSS3.

The market is constantly evolving, and the front-end landscape changes rapidly, meaning there's always something new to learn. As a result, I invest a significant portion of my free time in personal projects, allowing me to experiment with the latest technologies like Kubernetes and NestJS. Moreover, I'm an avid reader, delving into entrepreneurship and technical literature, which not only expands my knowledge but also provides valuable insights into the latest industry trends and practices.

In 2019, I started a business renting out a self-built photo booth. I personally developed the complete software and control system using React Native (iOS, Objective C) and NodeJS. Since January 2021, I've been working on a project that's slowly growing into a mini-startup - a new multi-vendor platform for meal preparation companies, launching soon.

I'm quite proud of this!

For over 10 years, I've been working for the coolest clients in the Netherlands
