Jessim delivered 2 seasons of training (CDA and DWWM) which went very well. Technically, he is very good, and the trainees also appreciated his courses. For a first training experience, it's great. We will continue to use his services.

Jessim worked for 2 months on the integration and refactoring of front components using an internal library based on our Vue.js design system for an internally produced SaaS.
Jessim is a remarkable professional: serious, diligent, honest in his work.
His good humor and dynamism are contagious.
He was immediately operational and quickly got into the code.
It was a real pleasure to work with Jessim, and I will undoubtedly work with him again if the opportunity arises.
