I am Joseph MICACCIA, certified network expert, based in Provence Alpes Côte d'Azur, France.

About me


With a great technical experience, in a wide range of skills, I am specialist in computer systems and networks. Proactive and experienced in the management of large structures, I ensure the proper functioning of the facilities by combining rigor, flexibility and security.

Certified network expert

Self-taught, autonomous, responsive, rigorous and with an excellent team spirit, I realized the implementation of numerous IT projects, notably related to the security of infrastructure.

And, within the framework of my various functions, I ensured the management of several teams. In addition, I actively contributed to the development of the PSSI.

Passionate about my job as systems administrator and computer networks, I also acquired software development skills, as well as management of around thirty sites of which I am the founder, the architect and the director of publication (CNIL, RGPD).

In addition, I have acquired good experience in dealing with cyber attacks since, having been faced in particular with a violent computer attack, I knew how to federate the teams IT to restart the company (3000 people) quickly and without sequelae.
