✉️ Do not hesitate to contact me for an initial discussion and further information. I am available.

🙋‍♂️ Background:

I started as a junior consultant in an IT services company, and my experience has led me to various technical environments. I have evolved in my roles (technical referent, lead developer, software architect).

Despite my experience, I am not interested in project management. The perpetual novelties and rapid evolution of recent years reinforce my interest in technology.

I now have many years of experience in consulting and development. I am available to intervene quickly and effectively according to your needs.

I also work on mobile front-end stacks (Flutter / Android) for my clients (example: technical migration of Android application versions, POC realization, or application with Flutter...).
I can also provide training if necessary.
