About Jean-Jacques

I am a web or windows application developer, self-employed since 2019.
I have the patience needed to maintain and evolve all existing applications.
I can also develop a complete application from scratch.

I practice various languages such as Delphi, C#, PHP, Javascript, HTML, CSS, VueJS and Visual Foxpro for the oldest.
But if your requirements are not in my professional background, the practice of equivalent systems, my perseverance and my adaptability will allow me to quickly reach the required level to succeed in the missions you entrust to me.

Whether it's occasionally to fill a resource gap or for a longer period on a large project, I am ready to consider any proposal you may submit.
