Hello! I am
My philosophy
I have worked in many sectors (telecom, blockchain, web, logistics, advertising…) and under strong production constraints. I have experienced both the industrial world and the startup world, which allows me to have a global vision of what IT is today.
What I realize in the end is that beyond technical questions, it is humans and the limits they set for themselves that prevent teams from evolving. The tools available to produce better and faster exist.
I talk a lot in my work.
A significant part of my time is devoted to deconstructing technical and organizational biases that trap developers (and decision-makers) and close the doors to efficient and stable production platforms while keeping costs under control.
If only what makes startups energetic and efficient could be applied to larger structures, even public structures, how far could we go with their firepower? How do these small structures manage to compete with the big players in the sector with so few human resources?
The cloud? Yes, but not only.
Many large groups try to create smaller structures, calling them “digital factory” or giving them names full of hope and modernity. They often try to break the inertia of the parent structure or the group by reducing the size of teams. Unfortunately, in many cases, the people put at their head perpetuate “the old system” in the new structure that sought to break free from it.
There is today this “old world”, with enormous inertia, too many competing teams, too many external people little involved in projects. How many very good ideas end with unfinished projects, poorly finished or worse, unused, or even abandoned before being completed?
In these scattered teams, we find many developers who no longer have energy to give and who come reluctantly to work every day. How does an industry that was created by passionate people, and that creates so many vocations, manage to extinguish this energy?
All this is not inevitable. The DevOps philosophy (like agile principles) was created to change this. Working in teams where people are happy and motivated increases overall productivity.
This is what motivates me to go to work every day: finding the tools to produce better, in environments full of challenges and technically exciting.
