Back to original languageAbout Gaetan
Passionate developer with about ten years of experience and expertise in systems administration, my professional journey is marked by an insatiable curiosity for technological innovation.
I offer web development, application, scripting, and DevOps services, as well as systems administration services. From IT management of your infrastructure to providing managed resources such as pre-installed and maintained instances. From cloud to on-premises infrastructure. I can travel to your site (throughout France or further upon quote).
I have about twenty client projects to my name and a multitude of internal company projects. To date, I have worked in various sectors, including medicine (through sleep apnea), retail (restaurants, small businesses), and industry (through my past experience). This allows me to adapt more easily to your business processes.
Do you have a development project or need help with your infrastructure? I would be delighted to discuss it with you.
