About Johann

Hello, I specialize in digital transformation! My passion: the intelligent and clean design of web applications.

After 8 years as a developer and lead developer, I had the opportunity to work with a nice panel of technologies - Front & Back, industries - from Renault to BRED, but above all, problems!

I am the one who makes sure your apps don't explode in 1 year.

Today, I focus on the Front and React!

The 2 missions we carried out with Johann went very well and brought a lot to our product. The design/refactoring tasks were not simple with a vast technical ecosystem and a very dense functional context to master. His attention to detail and the quality of the deliverable allow us to approach projects with confidence and to be confident in the durability of the developments carried out. He was also very invested and effective in onboarding other developers who joined the team. Thank you again for this excellent work and the relevance of your contribution!
