About Johan

---

Experienced web developer, I support you in highlighting your activity by creating high-performance sites designed to make you visible on the internet.

For over 10 years, I have been a front-end development engineer and have gained my experience with various structures, from small startups to international groups.

Specialized in designing UIs that put the user at the heart of the creation process, my areas of expertise are JavaScript development and the ReactJS library.

Thanks to my dual scrum-master skill, I have gained a step back from the code as such in order to successfully carry out pre-project studies, the reaction of functional or technical specifications, project management, the creation of progress reports...

Johan worked on the integration of new features on the front end of our Yunow application platform. These were features allowing the use of our platform in the creation of audio guides. The whole thing is developed in PREACT / JS. Johan was very efficient and quickly took control of the platform and the existing code. The result is up to our expectations, thank you Johan 👍 !
